screen sharing needed urgent

Hi,
there used to be a site called tradingrooms. You could set up a room and then share your screens or part of your screens with others in the room. The site no longer exists. Does anyone here no another similar site or software that could achieve the same thing - not just static file sharing but simultaneous live chart sharing
Thanks

I am using Teamviewer for the screen sharing and skype for the audio. Both are free.
You can also go skype - to tools - extras - there you have constantly new software which go with skype.

is a new privite share website. only limited is 10 other users

I've used Mikogo and found it very good http://www.mikogo.com/en/

Thanks guys - I'll check out your recommendations and see if they suit
