Well a few years back on usenet of fidonet, some OS/2 supporters stuck "Team OS/2" in their sig to promote OS/2.
Ofcourse us Amigans couldn't be left behind so Team Amiga was started =).
And what it did? AFAIK absolutely nothing, besides sticking 'Team Amiga' in the members signatures.
Actually I should still be a 'member' of Team AMIGA :-b. Perhaps I should put the phrase back in my sig :-D.
