BCS, IET, IEEE, Comptia ITPro and others

Hi All

Are any of you active members of a professional IT organisation such as the BCS, IET, IEEE etc? I was once an MBCS in the British Computer Society (BCS), but I left a few years ago, as I wasn't getting the most out of it. I will admit this will have been my fault, but I wondered if you had anything to say about these organisations?

Thanks
Jim
