There is a bug that only manifests in certain clients which breaks /LIST but you can work around it by /msg chanserv list. (I wasn’t seeing this when I tried with ERC tho.) I’ll see about adding a little IRC cheat sheet too; that’s a good idea!
/LIST
/msg chanserv list
Ah, talking to chanserv helped, thanks! I’ll give it a go when I’ll have the time.
