what version of the boards are you using on your site?
and, if you've recently upgraded, has that ever interfered with the actual content of your discussions?
i just converted my personal board from 6.1.0.2 to 6.3 last night. for the most part, conversations continued uninterrupted (as if no one even noticed the upgrade!! and i even bought matching shoes... !...)
i remember upgrading from the 5.45 days to the then-new 6.0, and that definitely caused a stir of sorts, and most of the conversations, at that point, ended up discussing the new look!
