For your first meeting, try having everyone write a short note on what they want out of the guild, and build from there. You could then make it what you all want it to be.
A quick, 'get to know you' game.- Take a couple spools of cheap thread, tell everyone to take as much as they want of it. Take a length for yourself, pass it around. Chat quietly while this is accomplished. When everyone has their thread, hold yours up, and explain that while they wind it around one finger, (demonstrate) they must talk about themselves, what they like, what they do, about the family, etc, until they run out of thread. Great fun, and you learn about each other. Really fun when someone takes enough thread to thread a needle or more...
