Cool (and everyone has to be a newbie at one time or another! I think we're all newbies in fact). I know some about POF and OKC; I'm curious have you tried PMM as well (PolyMatchMaker)? It's not as heavily populated but it's perfect for polys wanting to get to know other polys.
Sometimes it is helpful to make (platonic) friends with people in local poly groups, and one never knows when a platonic friendship will lead to something romantic later on. Googling "El Paso polyamory," or even "Texas polyamory," may yield some local groups you can join.
In the meantime you can make a lot of friends on Polyamory.com, and get a lot of good advice.
Good luck in your poly adventure!
Love means never having to say, "Put down that meat cleaver!"
