Recently, I've been noticing that the last line of the post tends to appear on the same line as the ------ over the sig. This looks pretty damn stupid most of the time, but it's a problem that pretty much just developed.
Also, the old problem (Waaaay back) of threads with 100 posts displaying 3 possible pages of posts but only two with content is still around, and that should require only a single line change of code to fix- namely,
(ThreadPosts / PostsPerPage) = ThreadPages
to
((ThreadPosts + 1) / PostsPerPage) = ThreadPages.
