Sorry to hear you had problems with this site. I've never contacted the system administrator, but you might want to let them know.
Personally, if it's a long message, I'll write it up in MS-Word first, which has spell checking. Also, I don't have to worry about crashes or glitches zapping my entry.
Something else worth doing on any web site is to periodically use Ctrl-A to select all text, then use Ctrl+C to make a copy in your Clipboard, just so you can't lose it.

Also, sorry to hear about the crappy brake job. Thanks for help getting the word out the CT sucks, and to maybe protect people who haven't found out yet just how crappy they can be.
