As you know, several weeks ago we made the choice to move our main IRC presence from Freenode to Libera.chat due to some changes in the management of the Freenode network. You can, of course, find details about that elsewhere.
Meanwhile, due to the name recognition of Freenode, people continue to show up every day on #centos@Freenode to ask questions, and are met with silence, because the experts have moved over to Libera. Those users are therefore not getting their questions answered.
The trouble is, Freenode has a policy that we cannot put the new channel location (ie, irc.Libera.chat) in the /topic, and attempts to redirect those people to Libera tend to get people scolded or kicked off channel, which further worsens these users' experience.
So ... all that to say ... if you are able to answer beginner-to-intermediate CentOS questions, and are able/willing to hang out on the #centos channel on freenode.net, your presence would be welcome. Network staff have confirmed that it's ok to send people to Libera.chat when we're unable to provide answers, but they would like to attempt rebuild an expert community there.
I'm hesitantly willing to assume, for the moment, that this is in good faith - there are, as far as I can tell, some good staff members left there, and, after all, this is about helping users.
