I have been added to the mailing list for www.networkingtimes.com. I can participate in free web seminars and I found them to be very informative. I just attended one last night and they had a great speaker - Laura Kall. If you ever get the chance to hear her, please do so.
Also, join www.karenphelps.com. This site also has conference calls and other events, which can be free. Some are with a fee, but most of them are FREE!
Hope this helps!
