Over the first couple of days, the site went from crap (sorry) to much more useable and lots was made of the tweaks going on in the background. The site speed did increase for a start.
Are anymore tweaks planned? I ask, because I think the site is running a little slower again. It's takes a good few seconds for the 2nd post to appear after the first, and then it can take a good few seconds for the Quick Reply box to appear at the bottom... =)
