VDVsx,
Thanks, but my questions were basically to admins and people who manage extras-testing process or who wrote those rules because I think that there should be notation in WIKI about announce thing. Right now it seems that it's just thing that some developers do and some do not and we might not be sure if it is just lack of information or just that developers just doesn't want to announce even thought he/she wants votes to get extras.

Why would anyone promote to extras-testing if he/she would not want to eventually go to extras? You can stay in development and just fool around there.
