Per an old Pinstadium email I recv'd, Pinstadium became an official partner w/ IFPA probably in late 2018 or early 2019.
I'm fairly confident that IFPA provided Pinstadium w/ email addresses of pinball players.
Looks like I started recv-ing Pinballstar emails around Oct 2018.
Not sure if they got my email addr from IFPA or JJP or elsewhere. ??
The last JJP email I recv'd was in early Dec 2017.
