Mistake! There was an attempt of an automatic insert of the message in a forum. Your message is sent to hell. Try still times who knows - can it will turn out? Still probably, that you too long wrote the message - then pass to page back, copy the text, update page, insert the copied text and press button "Send".
I guess this is some sort of security or something, but why do we have a time limit as too how long it takes us to write a post. There have been several times that I have to go and double check my facts so it takes me a while (cause I hate lookin' like a fool) and when I submit I get that error. Most of the time now I've learned to copy it before I submit so that I don't have to rewrite it all, but when I forget it is extremely frustrating
