[Callers] Callers Companion - how is it working for you?

Brian Hamshar mentioned this software in an email posted today. I would appreciate hearing from folks who have put this to use: Are you using the basic version, or the expanded version? How long have you been using it? Are you using it with a Mac or a PC? My husband is just taking up calling, and I've been calling and collecting dances for about 6 years now. We are wondering whether we could use one database for both of our collections; do any of you users have a sense of the workability of a combination database using Callers Companion? Thanks for your evaluative input! Karin Neils Grand Haven MI
