Is there a way to message a swap member?

Hello!

First of all, great project, definitely deserves a donation :).

I started a pentagon swap successfully yesterday. Today everyone seems to have connected, until I found out, that one member didn't connect to the right node. I already wrote a comment in the swap, but I I am worried he will not notice his mistake. (I am also confused, why he was rated positively without a connection)

Thanks for help!
