Twice in the past two weeks I wrote a message to the same FS user. After pressing the Send button, the message was not sent either time. After making the attempt the second time with the same result, I guessed that with this being about the fifth message between the two of us that perhaps our thread had exceeded a character limit. It would have been helpful if I was informed why my message could not be sent.
This pertains to the Messages icon next to the circled question mark on the main FS page.
