We use the IRC online chat system to coordinate projects and development of open source software.
If you are familiar with how IRC works, you can use any client to connect to irc.libera.chat and join the channel #arianne or #arianne-faiumoni.
Otherwise, there is a web chat client which is very easy to use: #arianne
The #arianne channel is publicly logged, so can read past conversations. Please stick around in the channel for a while after you ask a question or make a comment. It may take some time until someone responds.
