At the bottom of the guild list thread is a link to the wiki guild registry, which is more up to date.
You don't need a guild yet. When you first log in, you'll arrive on Silan, the tutorial island - all the gear and teaching you need will be there, and if you have questions to ask, you can use universe chat. If you need help with something, use region chat.
I suggest you don't join a guild on Silan. There are those guilds which will recruit on Silan... but to join a guild before you know its members, know the community at large, or even know the game probably means you won't join the guild which is best suited for you. And a guild has such a huge impact on your game experience, that joining the wrong one can drive a newbie away from Ryzom altogether. So take your time - you'll find people are always willing to help you whether you're in their guild or not.
