Okay,
For those that are having issues with the old editor (after we reverted back to it this afternoon), if you were able to use the new editor without a problem, or if you just prefer the new editor, you can still use it on the beta site. The version of the beta site is exactly what we had on the site last night and this morning.
You can use the new editor here:

WARNING: switching between the two different sites and using the two different editors may cause problems if you don't clear your cache. So, I'd suggest you clear your browser cache before you try the beta site.
