After a few days being down, it looks like the website is back up and running, and with some changes. Perhaps the most noticable is in the editing windows where there are some different editing options. It looks like spellcheck is still missing (except for Firefox 2.x users!) but there's a special character option (⇔!) and a few that appear to be tied to some advanced HTML tags.
Also stylin' is the new favicon, which some people may notice in the address bar, on the tabs, or in the bookmarks for the site. All the cool kids have one.
Thanks for the upgrade!
