In the upper right hand corner near the login area, select the 'Settings' option. Then search the Menu area on the far left of the page. Look for the section 'My Subscriptions' and select 'Subscriptions'. You then just follow and complete the Paypal steps.
After completing the paypal process the board will automatically move your account into the Super HoleShot Members Group. You will then find the Super HoleShot forums located near the same area as the Classified forums.
