With customizing, it's one of the few areas I view as "the more the merrier" with posting... I think cross-traffic with the niche isn't terrible, however I share your opinions of Rebelscum's customizing forums. They're not my favorites and after my impromptu banning at Rebelscum (and my impromptu reinstatement, neither with really much of any reason given for WHY), I can't say that I MISS Rebelscum at all...
It is a lot of "wow", with little more.
But, JediDefender's pretty established that we're not going to have a Customizing focus. I only highlight customs that I think have a broad appeal to the collecting hobby as a whole, and JD's not looking to build a customizing focus (that's not to say we're not EXTREMELY proud of our customizing community. To me it's a solid group filled with experienced customizers, novices, and experts, and all who share information... I'm impressed with it).
I think Customizing focuses are best left to the experts though, and that is
www.FFURG.com. The idea's sound, but it's basically the Critique of the Week concept that FFURG has run in the past. I think it's a good idea, and that FFURG is the vessel that can carry the idea. That's not to say we'll never change our mind, but right now we're focused on bringing news about collecting to the broader audience. I love customizing but I have to admit it's a niche within a bigger beast.
If minds are changed on this, we'll certainly let you know right here.
