I can't provide a complete list I'm afraid, that would require someone with a better overview of which OBS projects are submitting stuff to factory, but I'd guess we have at least the following significant teams:
X11 Kernel Mozilla Java Zypp OpenOffice.org Server Games
Though I'm not sure all of them have mailinglists and/or IRC channels, maybe that should be a prerequisite for being considered a real team.
While doing a bit of searching for this I also stumbled on: "board election officials" "goblin/moblin/meego/whatever-it-is-this-week" and maybe "radeonhd", but that should prolly not be considered an openSUSE team.
I am not sure here whether all these are actually or required or not . I would like someone experienced to express his opinions here . Henne , Bryen or Andreas (I have cc'ed them )?
I feel if these fall under OBS , then why not mention them as sub-divisions in the OBS team page itself . . ?
FYI , Openoffice.org has been considered as obsolete so it'll not be counted .
