Windows 7 Tip: 
Mikogo is very quick and easy to get started. The organizer just downloads the app, start a meeting from the system tray, and instantly receives the unique meeting ID. The invited participants then use this to join the meeting. No installations or registrations on the participants’ part. Mikogo is 100% with no hidden catches. It is free for everyone with no feature or time limitations.
You can use Mikogo for product demos, online meetings, online presentations, remote support, and webinars. You can show anything you want – in true color quality – to up to 10 people at the same time!
Features:
· Screen sharing
· Change presenters
· Remote Control
· Pause Transmission
· Application selection
· File Transfer

Hi Raj,
Thanks for a great post. I hope you and your readers enjoy free screen sharing with Mikogo.
We’re working hard on new features for the next version. I’ll keep you posted on this.
In case of any questions, feel free to send me an email.
Cheers,

Raj, I just saw your post about Mikogo and would like to ask you if you also could give TeamViewer (www.teamviewer.com) a try?
TeamViewer focuses mainly on online support of distant PCs and Macs. You can e.g. reboot the machine, record the session, change directions, present your screen, chat with your partner, open even a VPN (virtual private network)…
Just have a look at it and get back to me if you need any further information.
