Another session playing in the online collaborative solo west marches  style campaign called "The Pit" and uses my "Hexcrawl adventures"  supplement for BFRPG though any compatable OSR rules are permited.  Anyone can join the discord channel and view/edit the map and go play  out a solo session, updating the map as you explore and sharing your  adventure logs to further flesh out the collaborative world.   Join us at: https://discord.gg/mhk4kGpfuU
