There’s plenty of general tech comms and a load of programming focused ones, including a whole instance in programming.dev, but are there any that are more centered on Help Desk, IT, Sysadmin, etc?
For SysAdmin you can use [email protected].
For LinuxAdmin you can use [email protected].
I haven’t found one for IT and Helpdesk yet, but I am pretty sure they are out there.
maybe this one is interesting for you: [email protected]
Maybe also [email protected]. There are selfhosted communities on other servers too.
This one seems to have quite a bit of traction, though OP (is that still the correct term here on Lemmy?) would need a different account to subscribe to that instance with, as beehaw is no longer federated with lemmy.world for the time being.
Create or join what you’re looking for and post content. This is all new and some of the niche areas of interest just need a few active voices to kick off the community.
I have found the macadmins Slack-channel to be a great resource
Second this. That channel has saved my bacon more than once.
