I know this may be a silly question, but I have had a habit of missing these in the past and really want to join as many as I can, it just seems by the time I hear about one, it's already over. 
Is there a discord, or an official mailing list to track them? A place that announces when new jams are coming out and such? I know there are 4chan posts but I don't know if that is the best place to keep track of announcements and such.

I'm a bit iffy about making a discord. But I'm open to making a mailing list to those who want it. You can either post your email here or email me at littlehorseappreciator@proton.me asking to be included in the mailing list. This goes for anyone reading this
