A discussion popped up this morning about Slack and it's use in 18xx games. I wasn't sure if there was already a dedicated 18xx Slack team so I went ahead and made one. 18xxgames is the team name so please feel free to join if you'd like or shoot me a PM with your email and I can send you an invite.
How can you join without being invited? It seems the registration process for Slack requires either an invitation or creating a new team. I'm sure they have their reasons but it seems as backasswards as using a Yahoo mailing list to me.
