Is it me or something changed on the forums ? fonts seem to be smaller (much smaller - same with smileys and buttons of BBcodes) and the type of the font changed too (not sure) and there is no "lines" between the posts in the sub-forums / in posts etc ...
Nothing has changed as far as I can see. If you're curious you can just compare the pages with the archived pages on archive.is (but I don't think there's any archived reply pages.)
