About [[Phabricator:phabricator-people-148aaf2e06c62283/fr]]: extremely unsecure suggestion!
Nothing we can handle on translatewiki.net. Belongs into the Bugtracker of Phabricator. But: "Effective June 1, 2021: Phabricator is no longer actively maintained and no longer accepts bug reports." per https://secure.phabricator.com/book/phabcontrib/article/bug_reports/
Phabricator is maintained by Wikimedia itself in its own branch since extremely long. And this is is where these messages to translate on TWN are coming from (not from the initial branch that was maintained by a wellknown large company, but even before it landed its translation here in TWN!).
But what they mean is that various extensions to Phabricator are not all all used by Wikimedia and so can't be maintained. Anyway, Phabricator is still essential to all Wikimedia operations and has not any substitute to track bugs correctly, even if Wikimedia also uses Git an Gerrit, Phabricator is the only tool that federates everything). Phabricator is also used by other non-Wikimedia projects (including some whose translations are made here in TWN) running their own instances (possibly not all its extensions).
Have you seen Wikimedia seeking for another project management tool and testing it (there are some open source candidates, but they are proprietary in most of their needed extensions)? I have not, so it's very unlikely that it will be replaced soon.
Also I posted the mesage here, because Wikimedia (or you at TWN) has still not modified the Phabricator translation project to give a suitable place to send reports. This was discussed multiple times and no solution deployed for now. Each time I have to lookup into the Wikimedia Phabricator website to find some relevant place and forward a detailed link to this support page for details, and then post another link here to the place in Phabricator where the bug was reported. I did it several times even recently in June and early July. Wikimedia then responded here and not in WM Phabricator!
How do you want me to work differently and track issues correctly ? Using Twitter is not a solution, and there are many active daskboard in Phabricators with lot of things to do, and they are STILL active (even if things have slowed down). Why was it not announced before the "effective" date of June 1, 2021? Why don't they give any link to any alternate site or bug tracker? If this was true this would mean that Mediawiki itself would no longer be supported, and almost all translations made here would no longer have any support and TWN itself would die!
In fact I absolutely do NOT see this closure notice in the main effective Phabricator site (https://phabricator.wikimedia.org/), which is extremely active! Your link going to https://secure.phabricator.com/ instead is incorrect (this is an unrelated legacy instance that existed many years ago before Wikimedia took control of the project abandonned by a wellknown large company). It just means that Wikimedia will no longer renew that legacy domain name and will use Phabricator ONLY in its own supported subdomain using its own farm of servers, and that active synchronization between the two instances is terminated. All project dashboards and trackers should have been transfered (but there's still some work to transfer some old dashboards and some trackers are still active on the legacy domain, but with very slow activity).
May be I'll contact Akklaper @WM to change the notification currently displayed on the legacy domain, so that users are correctly informed as a reminder where to go (including you, because you probably used a search engine to find relevant bug reports and did not realize that the old bug reports you found were still pointing to the old proprietary instance and that they were not archived, transfered to the WM instance and adminsitratively edited to n longer reference the old domain; noly new bug reports cannot be submitted on the legacy instance, but it has still not been locked down in readonly mode to archive and transfer all its content, as there is still some response activity on existing bugs submitted prior to June 2021 and still not closed there). And anyway, TWN must find a way to have all TWN supported translation project with a relevant bug report link. For now the message given above jsut links us to this TWN support. And we still needto find ourself a relevant dashboard/tracker on the effectively supported Phabricator instance. This means there are work to do in TWN too to cleanup the unstable situation, possibly with development in TWN!
And as far as I see the "Phabricator People" board/tracker was changed in 2016 to point to https://phabricator.wikimedia.org/ (see https://phabricator.wikimedia.org/rMWVA456749069b2e5b138bb7ca89fad1225d2929ace0), i.e. NOT on the legacy Phabricator domain where it has NEVER lived (before 2016 it was on https://bugtracker.wikimedia.org/, which is dead since long; in 2014, old bugs related to the "Phabricator People" extension for Phabricator made by Wikimedia were still forwarded to the legacy "phabricator.com" domain before Wikimedia took control of Phabricator development and support, because the current "phabricator.wikimedia.org" instance was still not installed and running and the old https://bugtracker.wikimedia.org/ was still active). This also means that the "Phabricator People" board/tracker has always been managed by Wikimedia itself.
