You do fantastic work on the site and everyone appreciates it very much.
The character count was recently increased in the 'black box' IM chat windows which was a great idea.
A problem I have noticed is that they will let you continue typing past the new character limit without you knowing it - the result being cut-off messages at the other end.
If it was programmed to stop you typing any more into the window once the limit had been reached, this would be ok but would possibly leave you having to go back and re-word it a bit to fit everything in.

Thoughts?
