ya 100, but ive seen guilds that have like "name here" and then they have "name here 2" "name here 3" and they link them all through an alliance. (sorta)
We've done that, started with Wizardy Players Guild [WPG] and when it was max created the allied Wizardry Players Guild Two [wpg]. Now that Alliance chat is open it has worked great and [wpg] is up to about 20 members now.
