Long before social media became commonplace, there were list servers on the internet. These were text-only email lists that you had to subscribe to. Everyone that subscribed had the ability to post to the list so that everyone on the list could see their post. It was a great way to get to know other like-minded folks that shared a common interest.
One such listserv was OldTools. As a matter of fact, it’s still around and very active.
I learned a lot off of that mailing list and got to know a lot of good folks. It’s a tremendous resource. But over the years, I’ve had to back off simply due to the sheer volume of emails and the time required to read them.
