Interesting format, which I've used on other forums (fora?) and seem to have similar small irrits:
Scrolling to the bottom of the page to go to the next thread is a pain, we had the same feature at the top of the page as well as the bottom, in the old format.
Scrolling down too soon whilst the page downloads, gives a frozen scroll of the existing lines only, until download completes. Ugly.
My total post number is quite inaccurate, so no doubt others are suss, too.
Date of last post, rather than time since, would be preferable.
What's with the "rep" allocation?
Oh, and congratulations to the team that put it all together, it must have been a daunting task
Editing a post seems a bit clunky, too!!!!!
