I found this in the RLC FAQ's
How can I delete my posts from the forums?
After you make a post on the forums, you have three days to edit or delete it. Should you decide at a later time you would like a specific post or multiple posts removed, you will need to contact
techsupport@redlightcenter.com or private message a forum moderator/administrator. Please include the links of any posts you would like deleted and a short explanation as to why. We will get back with you as soon as possible.
