I think someone mentioned in QSF that they were able to see Trek headlines when using the Old Grey board style, so that might be it (if it hasn't been fixed yet, that is). Otherwise, if it's the Trek-related links at the bottom of the board you're seeing, that's because TrekBBS is our sister site* and I would imagine they want to cross-pollinate interest/members.
*which explains the glitch using Old Grey.
