We have a major bug within aptosid.com forums that is causing problems for new user registrations.
It manifests itself with the following notice:
"Error! An unidentified problem occurred while sending an e-mail message"
Whilst the registration is accepted, it will not allow a new user to login.
Until we are able to fix the issue the temporary solution, for now, is as follows:
With an IRC client: /join #aptosid
State your issue about registration and be patient, A response from admin could take minutes or hours, depending on time zones.
A member of the admin team will enter into a private conversation (PM /query) to help you.
