I'll have to give it some investigation. I'm pretty confident in the ability of end users to figure out a basic IRC client, but logging made it a non-starter for our use cases - the chatlog module you linked is rather basic, but looking at the source it should be easy to extend for our usage.

UnrealIRCD also has modules for this. You have to contact the site admin to acquire them. https://www.unrealircd.org/
