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?
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.
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.
I have found the macadmins Slack-channel to be a great resource
Second this. That channel has saved my bacon more than once.
maybe this one is interesting for you: [email protected]
