I just upgraded my Kareha version, and now I need to delete some spam posts, but when I click on the "del" link beside the posts, it says the Admin password is incorrect. Where am I supposed to enter this password? In the documentation, it says to click on the "manage" link, but I don't see any such link!

Also, is it possible to completely remove a post, instead of having to see the "this post was deleted by a moderator" message? My board has been hit really hard by spam, and now its completely covered in these messages.
