I do and I would be lost without it. I started out on Family Tree Maker but FTM was too expensive to maintain and didn't have features I wanted - like attacking photos and documents to my entries. After trying a few others, I settled on Legacy and have been well-satisfied since. I have been going with the idea of becoming a professional genealogist or at least a researcher or forensic genealogist after I retire and wonder if there would be a better alternative to Legacy. What do you use? What do you like and/or dislike about it?
