I like what I see!

So this adds CAP_MESSAGE_TAGS to the .h file but doesn't request it, is that intended?

it is, we use it to ensure if a server understands /expects tags as input, but we don't necessarily need to request tags going in our direction

that said we're probably going to request it in a future PR (soon)

I guess it's easily testable with /quote cap req message-tags

should be!

thanks for review!

@dequis can this be merged?

@irssi/developers

nice!
