If you have friends who used to be in separate circles but are going to finally meet, how would you handle that property?

Let's say, you all meet, you know each of them, but they know about each other very vaguely. How to introduce everyone gently and keep conversations going in a non confusing way? What are the dos and don'ts there? Personal real experience of "joining" friends would be nice to read about too!

A little bit about me -- I'm in my mid-to-late-20s, male, single, recently graduated college, and I quit drinking about a year and a half ago. I never really considered myself an addict; there was never a point where I wanted to quit but I couldn't and it never interfered with work or school. I just woke up one day and told myself, "I don't want to do this anymore," so I just stopped.

The problem, for me at least, is that I live in a relatively rural part of the world. There's not a lot to do here on Friday night other than go to the bars, which never really bothered me anyways because I work nights anyways and don't really like crowded scenes. Most of my free time is in front of my computer, I've recently started getting into distance running as a hobby, and I like playing board games when I can. All of this is fine except for the fact that I can't really seem to make friends in those mutual areas of interest without alcohol anymore.

I signed up for meetup, which seems like a great way to meet new people, and I'm sure it is, in bigger cities at least. But around here, both the closest board game meetup and run club are an hour and a half away. It seems like everyone around here just wants to meet up to drink, and maybe do some other stuff along the way. (Don't get me started on making my own events here -- crowded bars already give me anxiety so organizing my own meetup with people I've never met before would be a new, special type of hell)

I think at least part of this is compounded with the fact that since I graduated, I've had a hard time making new friends. I work a very isolating job, and teetotaling only further compounds the issue that I haven't met very many new people. It's something I've thought a lot about while searching for a partner as well -- I can't/don't want to meet people at bars, and I don't really find much use out of dating apps.

Sorry if this is unorganized or hard to read, it's just a lot of thoughts I've had over the past year.

edit: another part of it too is that, since I quit without the assistance of AA or any support group, I don't have any like-minded people to do things with.
