Here's the email I sent and got a response:
I don't use an ISP given email address, so I just gave him my hotmail addy. I would think you could just drop him a line similar to the one I did.
Hope this helps. If not, let me know and I'll try and get in touch with one of the other admins through the forum.
Yeah, like the vast majority of internet users, I have Gmail accounts for all of my email needs. I emailed that address from my official work email, hopefully that's good enough.
It's really too bad that they disabled registration like that - no other forum I've been to requires that many hoops to jump through - at worst it's been a couple of captchas, email verification, and moderator approval of the first few posts. That's enough to eliminate 99% of spammers, and it still allows determined individuals to get in.
