There was an attempt of an automatic insert of the message in a forum. Your message is rejected

What is this about? I've lost the message I was posting, with some effort.

Edit:
Just lost another constructed message - very unhappy.

I'm composing the longer ones offline now, then pasting them into the message box.

Roy,

Sorry for the occassional inconvenience with the behavior of the forum. Please attempt your post again if you experience that error. If you're getting deep into a message I would recommend backing it up to notepad before submitting. The error you experienced is possibly due to your session lapsing.

Thanks,
Scott
