Hmmmm. That sounds like a good idea, if you can find a good free MMORPG.
That's a big "if", because most free MMORPGs are crap. There's a huge difference between the free ones and subscription based ones. Personally, I'm looking forward to World of Warcraft, but I don't quite see how MIGC could "do" the whole MMORPG scene.
Mostly, we want fun and we want it now, and few MMORPGs seem to offer that, much less free ones.
It sure sounds like fun, but I think it'll have to happen outside of MIGC.
Signatures are for fools.
