I do that a lot on other sites that let you type in a long post, but then have a problem posting it. Or sometime I'll get their error message and find I can back up the browser to the point my post is there, cut it, fix the problem (usually logging in). and then paste it into the post window. CHB is nice in that it doesn't even show you a posting window unless you are logged in.

We're flying electric helicopters on Mars yet you can't turn on your clothes dryer in Texas. That's because scientists are in charge of Mars, and Republicans are in charge of Texas.
