It's too white. I don't like bright light and glaring things... but I'm sure it'll gather a bit of dirt and fluff and darken down soon enough...
It all seems to work fine, so far as I can see. I can post, edit, place links, place images and even make very silly noises at the screen... well, admittedly I could do the latter anyway, even without turning the computer on...
The only thing I CAN'T get it to do is allow me to edit my Profile for some inexplicable reason... Don't like those circular things, by the way, but having been given a huge, green, circular P - no vegetable references intended - I tried to alter it to something a little more "me". Yes, a Demoness with big boobs, you know the sort of thing... The little pencil appears over the portrait circle, it opens a window to seek out a picture, you select a picture and NOTHING HAPPENS! So, do the pictures have to be in some specific format, size, etc... or do we have to make them circular first?!
Anyway, everything else works, so not much to whinge about.
It could benefit from a clearer/bolder dividing line between posts, but that's cosmetic and can be hit with a big brick some time.
Have some small reservations about the Tag system. It seems simple enough but I can see an awful lot of people not bothering with any of the secondary Tags and thus the Forum ending up with massive gluts of posts under the main Tags. (I saw this was being muttered darkly about).
If it can be implemented on that infrastructure, I think a smallish series of Subforums under the main Tags for "Custom Content" "Scripting" etc, and no free floating secondary Tags, would make things clearer for those who weren't paying attention or just had some rabid Tagphobia etc.
