Just go to http://express.paltalk.com

Sign in as you normally would (or register).

A "room browser" will appear. Click music, then "live music," and find the
SmallTalkAtTheWall
room - provided that it's been opened by an admin, which it usually is early on
before the
Tuesday hoots.

If you have trouble, shut down the browser and restart it - that seems to clear
things right
up.

Only problem is that I can't find a "hold microphone" button - I can only hold
it down by
putting something heavy enough (in my case a souvenier key from the 1933 world's
fair) on
the trackpad button to hold it down.
