Some members have reported trouble in validating their account when they register on the forums here, usually it's the forums failing to send the validation e-mail.
To help alleviate this problem, I've been regularly reviewing the accounts helped up in the "validation" queue and pushing those through into regular "Member" status when I get the opportunity. This also follows true for those that are changing the e-mail address associated with their account.
If you've registered recently and are having problems, please check your member group -- your account may have been already pushed through to regular "Member" status.
As always, if you continue to have any problems you're encouraged to contact me directly at firstname.lastname@example.org.
