Just follow this example and post it in this thread:
[your gaia name] will join this awesome faction and be a proud G.E.N.I.U.S. supporter!
Example:
Beaucoups Of Blues will join this awesome faction and be a proud G.E.N.I.U.S. supporter!
Also, if you (for some odd reason) want to leave this faction, just come back to this post and put:
"I am un-joining this awesome faction. Sorry."
And then you are free. Don't worry, i'll be sad if you leave but i'll love to watch you go. haha. But really, I wont hold anything against you if you decide to leave.
SO, come and show your support! How can you say "no" to this face?
P.S. if you join you'll make Sammy happeh!
and nothing's better than a happeh Sammy, BADA-BING!
