Number of Members:
5/10 - 475 Members. I've seen better, i've seen worse. This is a good numbe rof members to have though, this many members should give you a wide range of members to post on your forum. Obviously, the more the merrier, although you've done well so far.
Number of Active Members:
7.5/10 - It looks like you've got a good handful of active members. 20 Members within the last 24 hours is a fairly good achievement, certainly better than some other boards i've seen.
Number of Posts (spam or otherwise):
10/10 - 89,741 posts is a fenominal achievement. All i can say is keep it up
Appearance (first impressions):
7/10 - mixed feelings really. I was initially impressed by the glossy headers and the clean layout. However, the topic icons on "last topic posted" don't fit in with the skin, and ruin the overall look of the index page.
Layout:
7/10 - A pretty simple layout. Not having too many sections makes viewing easy.
Moderation:
5/10 - Your forum is well moderated, although having an entire section not moderated is a bad idea. These kind of sections are often the trigger which causes members to leave your forum for one reason or another.
Activity:
7/10 - All your forums look pretty active, with a very large quantity of posts.
Overall mark (out of 100):
75/100. It looks like you've got a few things to do. I'd try and disable the topic icons from showing on the index page. Secondly, i'd start Moderating "The Pub", only to an extent where members don't go over the top when letting off steam.
On the other hand, the quick theme changer at the bottom of the index page is a good touch.
