I've noticed that membership here isn't increasing very much. I wonder if part of that is because the scrolling banner requesting email contact for account verification is so hard to see!! I myself registered twice without seeing it. Just a suggestion but wouldn't it be better to cull the spammers out by hand or add a better "Captcha" script in the original registration process.
I'm not unaware of the difficulties faced here. The registration script is key to allowing new members easy access.
Cheers
