There is an IRC-Channel called #hitchhiking on Libera Chat.
Be welcome to join our discussions. Many people come here usually to ask for hitchhiking tips and only stay for several minutes. Mostly nobody manages to answer in time. Please be patient and specific, show that you checked the wiki already. So instead of just asking "Do you have any hints on to get from A to B" tell about optional routes you consider or which info you found on pages about cities involved. Then everyone can learn a bit :)
If you are not able to join the channel, and get a message saying that "you need to be identified with services", then please follow the instructions here: https://libera.chat/guides/registration
For Finnish speakers; channel #liftari on IRC-net.
