I looked it up, last update was April 2019, but it was published September 2019?
Either way, it's been a little bit, and I never see anybody on it, so it might be worth it to contact him.
I like the system, and since it's free, I don't mind how simple it is. Especially when you compare it to the $20 minimum that >>272629641 costs.
If you're looking for realism though, they're definitely better.
