Nice engine in this thing. The backend is not as themeable as the front end, it seems, but I managed to copy my “other” site‘s theme in a matter of minutes. Purty cool.
I’d still love to get my hands on the writer of that damned calendar, though 
As mentioned by Donncha, I believe HTMLArea would be a useful tool for the backend.
Maybe I should stop chatting about revolution and just do it. I’m similar to the Judean People’s Front in that matter…
