Yes we can since version 0.80b1 :-) Drop TalkFM.68k.2 (available from the
same FTP-site as CU-SeeMe) into the same folder as CU-Seeme before
launching. You get extra Talk menu and from there choose: Show Talk Window.
You can type there and see what others have typed a little bit like with
IRC (Internet Relay Chat).
All you need is contemporary equipment ;-)
