To easily & directly access your clubs: make sure you are logged in & at your garage, now locate your "Groups" box. (It is located beneath your Motortopia image and member information on the left side of the page.) Here you will find all the enthusiast groups, car clubs, and business pages you are apart of on Motortopia.
Another trick I use, is to bookmark the moderators page in my browser. This way, after I am logged in, I can visit the moderator's page or my club page at any time.
