I am a member and have really found useful stuff on there especially a lot of actions that have really made my pics turn out really well.
I'm not as active a participant there as I am here, my sorry 10 posts and counting sucks, but I just don't see much to reply to there--
If you know that you will go to the site often then I say paying for it is worth it. I pay monthly and breaking it down, I pay $48 for 6months
for a site that I visit OCCASIONALLY, but it's nice to have and love the info.
