Posting Insurance, a Suggestion

Hello Technical Support,

A couple of days ago, I lost two posts. That is they never showed up in the system. I know it was probably user error, but I was wondering of there could be some way to double check with the user when they leave a text entry page that they initiated and contains text. Somehow "hotmail" does it. If I initiate an e-mail then attempt to leave the page, through either the browser navigation buttons or page links, I get a warning that my data will be lost. I believe it would be very helpful for all users.

Thanks, Dave...
