Working in IT for 3+ years, I’ve learned that desktop sharing/screen sharing software  applications make life a lot easier for both the users and for the  Administrators. It’s not only a great way to supply technical support to  users, but it’s also a fabulous way to share data and collaborate with  others remotely quickly and easily.Here’s a list of a couple of screen sharing  software. 
Remotely access your PC or MAC ! Yuuguu is  completely free and allows you to instantly share your screen with  anyone. Works well through firewalls also and on MACs.
 CroosLoop is also very easy to use, but requires that each party install the CrossLoop software onto their computers. Uses 128-bit encryption and allows for file-sharing also.
 Another popular service for remote desktop sharing. Easily access  remote PC’s by installing a client software onto each machine. Good for remote PC trouble-shooting, etc.
 A good free tool for online collaboration, desktop sharing, and remote PC access. No registration required, no logins, very easy to use. Uses SSH to make connections to other PC’s.
 SkyFex allows remote watching and remote control in real time. Does  not require additional software installation and works transparently  through NAT and Firewalls. Only for IE though.
 TeamViewer  has a couple of features, such as remote control of PCs, screen  sharing, file transfer, chat ability, and is secure. Have to install the  TeamViewer software for it to work.
 A free software that lets others watch your screen in real time. No need to install any software, which is a plus. Works with Windows, Mac and Linux.
 You can use all of the applications for all kind of activities, such  as boardroom presentations, group lectures, remote PowerPoint  presentations, computer helpdesk, whiteboard for telephone conferences, etc.
 If you know of one that I missed or think is better, post a comment! Enjoy!
