I wish to point out that IEEE is >not< open to just certified engineers. I was never certified (which means that in many jurisdictions it would be illegal to call myself an engineer), but I have been a member of IEEE for over 27 years. Even more interestingly, you can become a member of an IEEE standards committee without being a member of IEEE itself. Many members of IEEE 802.11 are not members of IEEE.

I think this IETF discussion list is like a combination of the IEEE and the ISOC : the IEEE is limited to certified engineers, while the ISOC is open to all netizens.
