Warning: the following is a rant.
The subscribe/unsubscribe system could use a bit of improvement HTC.
Its impossible to unsubscribe and resubscribe keeping your same username,handle, etc etc.
Once the costumer does resubscribe, it becomes a tedious hunt of e-mails and try-to-catch-HTC-online cat&mouse game to see if its possible to get back the old online callsign.
