I apologise for the wait. If you're keen to try the site, feel free to PM me the email address you signed up with and I'll get an invite out to you today.
We're not actively advertising the service at the moment. I just wanted to provide some context for anyone who finds this thread.
All remaining invites are going out in the next few days. After that we'll open it up to general signup when we think we can handle the traffic.
Cheers,
James
