His address is listed in the directory of this issue and he'll be happy to hear from you. Attend the Federal Documents Task Force Work Groups. This is one of my favorite recommendations for new members. The Work Groups meet Sunday mornings during conferences. Generally there are 5 or 6 discussion groups on various topics.
People can volunteer to be recorders for groups and to help with the follow up reports.
And of course, a sure way to get involved is to run for office or volunteer to serve on a committee. As one who has both won and lost elections, I can tell you it is a way to get your name out there guaranteeing when people meet you, they'll remember you. Committees and Task Forces have been busy. The web pages and announcements to lists are the overt signs of activity. The one item I will highlight for you is the work of the Ad Hoc Committee on Organization.
