OK, I downloaded IE6. I see what you mean.

Here's the problem: the forum pages are served by templates stored in the database, sold to me by vbulletin. It would be really difficult to go close all the bold tags. Probably, it would be better to just to upgrade vbulletin.
But, that probably isn't so easy, and may not be free, either.

All in all...This is not something I can fix real soon. I already have lots of piled up work, and this is only annoying, not fatal. So, I will put it on the todo list, but not at the head.
