Yes, Project Managers, don't be a lone wolf. Join the pack. Everybody ning along.
I'd like to introduce you to a social networking site made just for Project Managers. I just joined and became member number 2467, and you can see my initial profile here: http://projectmanagers.ning.com/profile/RichMaltzmanPMP . This is an example of social networking from Ning. Ning, Chinese for 'peace', was launched in October, 2005 and was established as an online platform for users to create their own social websites and social networks. And, on Ning, there are several networks for PMs, the largest of which appears to be the Professional Project Managers Networking Group. To sign up, go to this site: http://projectmanagers.ning.com/ . Once you do, you can take advantage of what appears to be a very active forum, join subgroups, even look for job opportunities.
So don't solo, ning along! Don't worry. You won't have to buy one of the outfits shown above.
