Gday! Always good to see new peeps. Although your profile picture could use some work. ;)
Oh how I envy you, and your fresh perspective with tribes! I was around when they started the creation of the tribes and it was a thoroughly exciting time for the whole community. And in a big way, a lot of that excitement is still living on even today. The tribes are great.
Hellmoon made a Tribe Compendium which has all the info on tribes you'd need:

Don't forget to leave a 'like' for Hellmoon if you check it out. :P
