Did Traveller have its own Usenet and/or Echomail groups back in the day?

Basically the title. I don't see a Traveller group on Eternal September, so I suspect even if it was a thing on Usenet, it's not anymore. I'm not sure how to perform a more thorough check off the top of my head.

I have no idea about Echomail.

If they existed, what were these communities like? Do they still exist and I just didn't find them when I looked?
