We use a program called contact plus, it's an access based program.  I think for the membership it works ok.

There is NO database program more flexible or more usable than FileMaker Pro. NONE. It has number-crunching capabilities too, although for accounting Excel is probably better. But mailing lists, personnel files, contact-sheet forms, multiple-term retrievals, all are very easy, and setting up the basic data files is straightforward and simple. I don't work for FileMaker, but man oh man do I use it! It has both Mac and PC platforms. Probably filesharable by now, and maybe for a long time already--that's one thing I haven't needed to try.
