Thread:Support/Email notifications

I think that the current default settings for email notifications don't make much sense, it's easy to forget to change them assuming that they're what you would expect. I propose to switch to true by default: currently both false. At some point in the future it would be nice to do the same for: when the enotif change so that it's not too spammy to translators. Actually the first could be switched to true anyway, to make Special:Watchlist more useful: one never knows if a correction to someone else's translation will ever be seen by them in their watchlist if they happen to look at it (which mw:Help:Extension:Translate/Statistics and reporting suggests should happen)...
 * "E-mail me on replies to a thread I am watching",
 * "Watch threads that I create or reply to",
 * "Add pages I create and files I upload to my watchlist",
 * "E-mail me when a page or file on my watchlist is changed",
