We belong to CASE, and participate in their listservs. Also UWebD listserv. We speak often at CASE, American Marketing Association, National Association of College Admission Counselors, National Association of Graduate Admission Professionals, and Graduate Management Admission Council events.
Beyond these industry-oriented organizations, we do a lot of reading/participating in more functional virtual organizations -- YPulse, A List Apart, Clickz, etc. all seem to be great resources for our work.
Let me know if you want me to screen capture a list of RSS feeds, etc.
Member of CASE and CNAC (College News Association of the Carolinas); lurk here and on the uwebd listserv; resubscribe (and then unsubscribe when I just can't keep up with all the messages) to several other listservs; most of my "real life" stuff comes from RSS feeds (compiled, and continually updating, at http://www.netvibes.com/newsace#Higher_Ed_Marketing_%2F_Graphic_Arts).
we are part of CASE and PRSA. i personally subscribe/participate in several web based things. i think a lot of people are part of orgs but do more participating through listservs, google groups and other things like that.
Hey Susan have you seen HighEdWeb? They run a big annual conference and you can join by email. I haven't actually been to their conference it yet, but I've been told that it's one of the best for Higher Ed Web People and have every plan of making it this fall.
Another one is Higher Ed Experts which is an extension of CollegeWebEditor and probably worth checking out. They run lots of professional development webcast throughout the year so it's easy to find one that fits your needs.
