Why are we calling it the Dark Side to begin with. I am compelled to call it the Light Side. Everyone seems to act in a better community spirit on some of the other sites. This may be due to the fact that the majority of those using the other sites have the same things in common.
At the end of the day you can support which ever site you want but if the organizing party only accepts registration from a particular provider than that is where you will have to go. I will continue to use several different sites until I decide (or others for that matter) differently.
At the end of the day it is up to you.
