I created the Network Opportunities page after I was involved in a layoff. Going to Professional groups is a good way to network. They say the best way to get a job is through networking, I got my present job by contacting a former coworker. While I was looking for networking opportunities for myself I saw that finding them was a long process. I saw an opportunity to help others and to do some web development, kind of a hobby.
The Groups for Networking Page contains many networking opportunities that I have no interest in but I hope it can help others. You can find the page through a google search and a large self help group has a rotating link that often points to this page.
If you are interested you can continue to the page otherwise go back.
