I actually kinda like the idea.
For the O Guild, I would say that any member that would like to run some of their characters in a Role-Play guild that they should just talk to MadMage or PM me just so we and other members know what's up when we see your RP character on. I would just ask that you don't wear the O Cloak on your RP character, that's all.
I imagine that RP guilds have their own rules about what resources that will be available to their RP characters so that things remain level. As far as I'm concerned, it's up to the RP guild master to let his/her members know if Members of the O Guild can us O Guild resources on their RP characters.
Personally, I sort of have a gnome fetish and I was actually thinking about running an RP character in that new Gnome guild. I've been doing O Guild for so long, some playtime in an RP setting would be kinda fun I think. Not that I have applied for membership or anything, just sayin.
