I just looked and got this
We are very sorry!
At the moment, there are at least 94,300 registered users at
www.dimeadozen.org, the maximum allowed under DIME's current configuration.
However, free slots become available for new users daily as inactive accounts are deleted. When DIME has fewer than 94,300 registrants, new users can sign up. Please note that the statistics on DIME's web site are updated every ten minutes; therefore, you may see this message even if the web site reports fewer registered users than the maximum.
Thank you very much for your understanding.

so i'll leave it a few days
