I have bookmarked the link
http://www.korat-info.com/forum/search.php?search_id=active_topics
and open the session with that. So I get a fast impression what activity there was on the forum, which topics have been posted to or opened new. That can be used by not logged-in visitors as well. Is much better than the "new posts" button that requires to log in.
On the "prosilver" template which is default people with visibility problems can click the engraved white "A" above "login", first click activates, second enlarges the script to big, third elarges to very big, fourth resets to normal etc.
