Internet Relay Chat is a protocol for textual communications. Basdon has its main channel #basdon and echo channel #basdon.echo on the irc.tl network (connect to chat.irc.tl). Chatlogs can be found at https://static.basdon.net/chatlogs. New to IRC? List of IRC clients. Administrator users can be recognized by symbols @ or & in front of their name (modes +o and +a). Owners have a ~ symbol in front of their name (mode +q). IRC has no offline messaging.
If none of the above works for you, nobody is available, you want to make sure your message ends up with the owner, or you simply want to make sure that someone reads your message (eventually), you can also send an e-mail to: firstname.lastname@example.org.
