It is possible that you have not successfully confirmed your e-mail address. First make sure that you have received an e-mail upon registration of your account and that it did not end up in your Spam box or automatic categories/filters.
- Solution 1
Go to http://forum.paradoxplaza.com/forum/register.php?do=requestemail - Solution 2
Try changing your registered e-mail address (you can change it back again immediately) and check your inbox (including the spam folder).
If you then change your e-mail to a nonsense one and then back to the one you want, the forum will send you a new confirmation email to the address you want to use. Act on that new confirmation email and you are done.
The other reason you may lack permission to post in forums, in particular support forums for specific games, is that the relevant games have not been registered to your forum account.
