I am unable to post comments on my friends walls or send private messages. I DID use an "adult" word in a message but as it was between consenting adults I thought it was ok, if this is the problem, I apologise for the use of it. If not, then can anyone please help. After I type the message and click send, a notice comes up saying " box cannot be empty ". Thanx to anyone who can help ... and I promise to watch my comments in future.
