To my knowledge the only issues remaining are the below issues due to scaling the forum in your browser. If something doesn't look right force a full refresh and clear the cache for the site on your browser. Sometimes you may need to do it a couple of times on different pages. This should fix itself on its own in a day or two regardless.
What I still need to do:
Figure out what to do about the font discussion
I'm not sure how long it will take, but at least one hour and it shouldn't take more than 3 or 4. Some settings may change in the forum, especially in terms of styles. I'll do my best to fix these up before going back live but if anything takes longer I'll fix those up later.
I'll update the banner as we go, but at various times the site may be completely down.
Edit: If anything goes wrong bookmark this url: http://maintenance.icmforum.com/ which I will use to post updates if server issues arise.
Edit: DEC 12: OK, the forum is updated. As you can see the style sheets did not transfer over.
Known problems: video/twitter embedding isn't working. I know where the issue lies but I don't know specifically what the issue is. I hope I can fix this soon.
To my knowledge everything else should work fine. Let me know here if you notice anything not working.
Visual problems can be reported, but they're probably style sheet issues. I have a huge list of all my previous edits to rundown over the next few days. Visual problems includes: colours, borders, links in the wrong place, smilies in the wrong place, etc.
