As a regular user of Teamviewer, both at work and for helping the users I support via my private business, I find the use of screen sharing software invaluable – having someone SHOW you the nature of a particular issue is so much more straightforward than struggling with the terminology to explain problems over the phone or email. However, it just got even simpler! Check out join.me for the easiest way to arrange screen sharing. These guys clearly know how to write a good interface! Thanks to Karl @frogtrade for the tip-off!
