Do you already have a tracking software program? If not I'd suggest Degei. I've been using it for several years now and absolutely love it! As far as ID's go, I personally do something to the effect of MOJ_FEM_09_1 or PPHG_FEM_10_3 so the first one is a 2009 Mojave female number 1 and the second one is a 2010 Pastel Poss. Het Ghost female number 3. Hope this helps!
