I think about writing a site tips and tricks post just about the time there is a new VBulletin release or major feature change. Probably one of the most important tips is to automatically get emails from any post you subscribe to (which can also be automatic for any thread where you participate). If the post are long. you won't get the entire post but you will be alerted to additional information being posted. The feature is nice in that you won't be bombarded with junk mail as only the first new post will be sent.
