Hello,
Looks like you found out how to get your account unsuspended, as it is currently not suspended and your site seem to work just fine.
Note that if you use the "keep me logged in" feature it may be take a couple minutes for the system to mark you as being here and active, if it keeps recurring try staying on a few minutes and check "News and Announcements" for any news that might be.
There's also an option to remove the need to log into the forums to keep the account active;
Prime Membership
