You can meet other helloSystem users and developers at
#helloSystem:matrix.org from any Matrix client (such as the Element web-based Matrix client). This Matrix channel is bridged to the IRC channel #helloSystem on irc.libera.chat. Joining via Matrix has the advantage that you will see responses that you may have received while you were offline. So after asking a question, you can come back in a day or so to see if there were any responses.
In any case, please stay in the channel for a few days and do not expect to receive answers immediately, since we are all volunteers.
