Hello and welcome. I’m Kevin Frank, and I’ve been using FileMaker Pro since the late ’80s… professionally since 1995. The expression “hack” has both positive and negative connotations. Here it is defined as “a tip, trick or technique that helps you solve a problem,” and the best hacks are the ones that can be re-used and modified to meet a variety of challenges. Or, put another way, as I read recently in Street Fighting Mathematics, “A tool is a trick I use twice.”
