It may be overkill, but find EVERY cookie for satelliteguys.us and delete them. Depending on your browser, it's often easiest to just search for "satellite" and see what results you get. For me, I get satelliteguys.us, www.satelliteguys.us, and store.satelliteguys.us.
Dump them all. I'm not sure what the cookies for this site do but one thing is just to keep you logged in (hence the 'keep me logged in' checkbox). Otherwise, everything else related to you is part of the database (subscribed threads, forum options, etc).
