Internet Relay Chat (IRC) is one of the original immediate communication methods on the internet. They served as a model for the well known "chat rooms" that came much later. When connected to an IRC channel, everything you type is propagated to everyone else in the channel. It is an excellent way to get immediate support or just shoot the breeze online.
On occasion PLUG hosts virtual meetings in the channel.
One of our members maintains an IRC channel for PLUG on Libera.chat Point your IRC client at:
Server: irc.libera.chat
Port: 6697
Channel: #plugaz
Use SSL
There are several who are there, seemingly, 24/7. Remember that it is possible that the people connected in the channel may not actually be at their computer. Be patient waiting for a response. If you have specific needs to be addressed, it can be more productive to request help in the email list to meet in the channel at a specific time.
