Actually I've decided to not use icons for the subforums, it doesn't look that nice and is way too time consuming. Instead the icons will be used for the catalogue thread and eventually be implemented as smilies.
I have also decided to not make the min/max stats of an item a top priority as they are not essential in order for the forum to function.
So to sum it up we just need to make subforums for each individual item and we can launch the forum.
Anyone interested in helping make the subforums just reply and I can give you admin.
