Changes to Special:SupportedLanguages
If you wanted to add a sentence to the header about Adyghe also being supported, you could. This is the only language that the software doesn't display on SupportedLanguages, as far as I can see.
What's the status of this project?
The remaining part is to finalise and add a new header to the page and to prepare that for translation. I'm sorry to say that I don't have the time to learn how to do this at the moment.
If you can provide the text, I can implement it.
OK, here goes.
This page shows a list of all languages supported by translatewiki.net, together with the names of the translators working on that language. A translator's name appears larger, the more edits the translator has contributed. The colour of an underline indicates how recently a translator has been active here, changing from red (last edit more than 180 days ago) through orange and yellow to green (last edit during the last 60 days). Click or hover on any name to find more information.
If a language is not listed, you can find out how to start a localisation project for a language at "New Language". Or check our list of languages already set up, which are waiting for translators to work on them at "Languages without translators". You can join our translators here.
If you translate to a language and your name is not listed, please add your name to the list of translators on the portal for that language. Use the following format so that the software recognises the name: * {{user|YOUR USERNAME}}
Please note that Adyghe is supported even though it is not listed below.
Please edit as necessary. I wasn't sure about the conditions for the colour green for example.
Just FYI: Adyghe is not supported. The code has not been set up.
