#nblug IRC Channel
IRC is Internet Relay Chat, and is what people used to communicate with text and keyboards through the Internet in real-time before Telegram, Discord, and ICQ existed. It’s a standard protocol, so there are many client applications and networks to connect to.
The official NBLUG IRC channel is #nblug on the network Libera.Chat, where several members will often hang-out and generate idle-time. Many of the members will join this channel (room) and leave a session logged-in even when they are away from their computer. Occasionally, someone will check to see if anything has changed, and may choose to chat.
If you join and say hello, only to find silence, try waiting around for a while and see if anyone else joins or responds.
