Having issues with P.M and Chat with the answerMug, how to fix that?

Nanoose & Element 99, I clicked in the 'Chat' shown on bottom right, then I typed in & entered in the Chat message, & even clicked on your Element 99 avatar in it just after I typed in the Chat, then I still didn't see any further message from either of You since then-even after about a day later from that too.
How else should I get more responses from the 'Chat', & from 'P.M.', only if I find who else would like to get more Personal Messages to theirs?
