There should be a function in the Forum to use Ticker Tape style announcements. These are prominent at the top when ppl log into the Forum and can be used to highlight time sensitive information such Gift Codes, New Feature threads etc.
Can't remember if it was a built in VBulletin 'feature' or modded by the them Forum Manager but we used it in an ISP Forum to highlight important Surveys, Competitions and Major outages.
