I know there's been some issus with site performance over the last few weeks.  I've been trying different things to fix it.  I've made some changes this morning which should improve things.  These kind of problems can involve a little trial and error before they're resolved, but I'll put in some extra time on it and should fix it pretty soon.

On another note some people have mentioned that the new version 30 of Google Chrome doesn't work with the site editor.  I've confirmed this, I updated my Google Chrome version from 29 to 30 and between those versions the forum editor stopped working.  I've tested several other browsers IE10, FF 24 and the Safari on IOS and the editor works fine in all of those.  So until I find out why it's not working in the latest Google chrome just avoid using Chrome 30 on the site.
