I have been using Filemaker Pro as a database for my inks and fountain pens. Many folks on the FPN have brought up the issue of keeping databases of their various pens and inks. One free one that I'm looking at if called Air Table. It is like a large, online spreadsheet that acts like a database. There is a free version, which should be enough for anyone using it track this sort of information. If you need to go over the limit (thousands of pens and inks?), there is a paid version. The problem with my Filemaker database is accessing it from multiple sources. It is in Dropbox, but I invariably end up with 10 copies of it on various computers and pads. If you are interested, give it a look. I am in no way affiliated with AirTable. I just notices it on a Facebook ad link, and it seemed like a good solution. Click on the Guidebook on their site. It will give you a brief view of how to use it. Jeffery
