The usual IRC disclaimers apply:
* Some/most channels will require some form of NickServ registration. So you might want to talk to @NickServ:libera.chat first to register your desired nick.
* You can change your nick via the @appservice:libera.chat bot that will open a chat with you in your first interaction with the network.
* Being joined as a non-registered user into #curl I wasn't allowed to change my nick. Leave channel -> change nick -> register nick -> join #curl.
Isn't #IRC great?
Also the #libera.chat homeserver has a matrix room directory listing 😍.
(You can add that to your client in the dropdown menu where it says "Matrix Rooms (libera.chat)")
