After Trustmaster said subforums are a burden to the forums (not much but still a burden) i thought of doing:
-On the forums.php (main part) add one more sql query, like html cache feature, we can cache all the subforums under like sed_forum_sections>column fs_subsections.
-We can change the subforum title function like
function....(..., SUBFORUM_ID, SUBFORUM_NAME);
btw will this be better (look at stupid coder :)), i mean faster, you know, now we only give id, and call title, whatever.
PLEASE NOTE: I did these, just asking if will these be better, if they are, I can commit a revision immediately.
