you can make a "ibis" whatever you want in any game, but it's not recognized nor official in the eyes of the clan or community as only clan have the right to lead anything with the ibis tag. also, 95% of the people in this community who played D3, have quit... them releasing a guild option isn't going 2 make anyone start playing again. I play often, but could careless about guilds in D3...
do what you want, but if you do make one, it has no ties with the real ibis... as in this community/clan. we also have a diablo 3 thread in the steam section...
