Our registration system was offline last week (little did we know) because I forgot to setup any mailing functionality on our new server. This is something that normally comes all setup on a shared hosting plan for you but when you are handling your own box from start to finish it is something you have to handle yourself. New server and a new education in server administration for me. Sorry!
This has since been fixed and we deleted all of the accounts that were created but couldn't receive emails (therefore were never able to initially login).
