Communication Tools

Want to show a friend/relative/grandma how to do something on the PC? Sometimes it is easier to control their PC remotely instead of giving the instructions on the phone.

There's already a program that does this (comes with Windows), it is called Remote Desktop, but how many people know how to setup the router/ports/firewall necessary for it to work? 

Skype is very popular but shockingly not many people are using it to their advantage. By using Skype you could save lots of money on long distance calls especially for those who travel frequently.
