Recently, I've spoken with a poet who doesn't track them at all. I've heard from people who use Excel, and I've also heard from someone who uses index cards, a system he started before the digital age. It works for him. For me, it would get heavy.
In my new video, I show my (super-simple) solution. I also include a bad joke and some flying SASEs.
Take a look, and let me know how you track which poems are where, what's rejected, and what gets accepted.
