Hello,
since you have already unsuspended yourself, I am not able to see what was your suspension reason. However, I suspect it was for inactivity. It is a requirement that you log in the forums each 31 days to keep your account active. However, you must stay some time logged in to make sure the system picks up your visit. Viewing the new and announcement thread is usually a good idea. Also, when you go to unsuspend yourself, you must have already logged yourself in the forum or self the system will simply re-suspend you, as no new visit were logged.
