RE: Receiving posts direct to my e-mail address
IIRC, this can happen if you have accidentally 'subscribed' to the thereads in question.
Check the threads, near the top right hand side there should be a link that either says "subscribe" or "unsubscribe". If it says unsubscribe, hit it !
Failing that, you can PM Marc at RCU id "RCAdmin" if none of the mod's chime in to help out soon.
