Kakaze, thomas has still been around here - not so much on the open forums, but behind the scenes.
I love that you guys all care about the place enough to want to help - but let's not start sniping at each other - it's not one specific person's fault that 3DG has slowed down, and it's been happening for quite a long time.
My best suggestion for now is to keep posting, and keep being active. I'm curretly recruiting some members to post more content specifically designed to inspire communtiy involvement. But if you have something particularly stimulating to share, please don't wait for me to contact you - just post it, and let's get some buzz started around here.
