Chat:	The #hledger chat (~140 chatters) is the best place for quick help and feedback. Join Matrix and the #hledger:matrix.org room in your web browser, the Element client, or another matrix client. This gives a persistent chat log and the richest experience (especially with Element). Or (same chat, older tech): join the #hledger Libera IRC channel in your web browser or an IRC client. You may need to register to speak. There is also a general #plaintextaccounting chat (~100 chatters): #plaintextaccounting:matrix.org or #plaintextaccounting on Libera.
