i hosted a "room" there for many months/several years.
this was usually on thursday nights..sometimes we would
be on their for so many hours that the sun would rise and
set in several time zones while we were there.
Frank from Toledo (francy) showed me how to do this
and many of us have spent countless hours singing and
playing to each other from all around the globe.

It was not compatible with MAC computers last time i checked.

i had a room called mudcat live acoustic jam.

the live rooms are the best, but beware you may find lots of
people on there just playing thier c.d's for each other...
or doing karioki (sp?)_ sing-alongs

you can use cameras on there to send a video image
but i never activated this feature in my rooms, as
the music that we hear is the main reason to join the room

and people often abuse the camera aspect for distracting activities.
