Well, I'll give it a shot.
Looks: It seems a facelift is already on order, so the aethetics are taken care of.
Speed: Forum is thankfully rarely slow, so no worries there.
Content: Brought in by people from all walks of life, so the only way to control this is with rules, mods and admins. And that seems under control.
Quality: Some posts shouldnt have been posted, but then theres and ignore feature. It seems however there is discontent among certain members but it seems in fun.
Feeling: Not yet a hard, cold living room, but not as warm and happy as it used to be. Reading around, some members feel the living room has hit an all time low.
Other: Perhaps a limit of smilies per post? And also for some, a compulsory read of the nettiquette sticky.
But most of all, it is imperitave that people understand to use the search and to respect each other. How to go about this Im not yet 100% sure.
Give it a month, then see how it is, and if it hasnt, 'improved' then and members seem to be causing the disruptions, PM them and try and work it out.
Failing that there is a ban option, but that is quite a heavy punishment, even though it seems its the only other option, rather than moderating each and every post.
