We need to stay in touch with those we can help, as well as those who can help us.
Skype is the best communication method I have found yet! It’s free and it does more than you would take the time to read if I included it here, so just GET IT!
Once you get Skype installed, make sure you leave your status as Online so people can message you even if you are not there! It will leave a little icon in your Taskbar to notify you. I leave mine Online except when I am shooting a video and never feel like it is a bother.
If you get people that do bother you, it’s simple to block them and you can set your configuration to only receive calls from those you want. Most of the time I just use it for text chat or screen sharing.
If you have a reason to contact someone fast, this is almost as good as a phone call if they are online.
