Well, I've done some checking and apparently there is a "flaw" in the way the forum payment is set up and there is nothing I can do about it (Except add it as a bug report to the makers of the forum software)
This is because the forum allows both recurring and single payments to be used. No matter what kind of payment you set up, the forum software will apparently send you a reminder that your RWG Supporter membership is about to expire.
If you would like to cancel your current subscription, there are instructions on how to to this here:

If you then would like to set up a 1 year or 6 month membership, go here:

thanks for your support
