When i tried to register a account its says
At the moment, there are at least 101,111 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 101,111 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.
So i think no one has invite to this site.If anyone has a invite i would like to have it otherwise if you not using your account i can take it please.This site also allows you to delete your existing account so that new members can sign up.If you not using your account please delete it http://www.dimeadozen.org/account-delete.php
