Hello, I was reading in "Magic of Fearün(sp)"
and amoung spells and magicily crafted items is a section about mage guilds. The book makes it out to be sort of like....a an exculsive club with a large falicity(sp) and most are really class specific e.g. mages, thieves, fighters. but to join you have to give a one time payment then a few very small payments. So "Blades of the banshee" could give member ships to all their members on someone's persistant server then charge other on-line people for a membership
As with forum guilds that is more like a clan, people you set rules leadership etc. with.
I hope NWN comes out with very little bugs unlike the new pools of radence(sp)(also I'm not the best speller I've noticed)
