Code Issues Releases Wiki Activity

ok, a slightly modified posting.php, some fixes too. topic-review and polls will re-appear shortly. Posting is a little bit screwed up now... will get fixed soon too. posting new topics/reply/quote/preview and edit works partially (the post get stored. ;)) This commit is to show the other developers the changes. ;)
