Subject is too long (max is 50 characters).

That tells me its an user related error.

It clearly states Subject is too long

So you must have been dumping the text to the subject and not the body. Of course its possible that the board software is fubar somehow but it seems if that were so we would all be getting the error.

Maybe some of you don't realize that [tab] jumps from one field of input to the next and [shift tab] does it in reverse?

Just from what I see from your error message.

Cheers.
