It is all good but there are a few little areas that could be better :
Have all the posts on one page, dont like the drop down to go from page to page, would rather scroll.
The background would be great in the pale blue used on the homepage, leave the actual post background as white but the whole background as blue, maybe ?
Does there have to be a gap between each post ? Cant it just be continuous ?
Oh yeah, and can we show our car details and have an autosignature to include photos of our car maybe ? I am not sure as to what the software will allow but that would be very good.
Dont want to sound ungrateful because the new functionality is great but I think I prefer the look of the old forum, be great to have this with the new fucntionality but all in all it is great !
