IRC network Umbranet which focused primarily on music is shutting down, but instead of turning off their services completely, they've allowed Slacknet to take over where they left off. So in a way, Umbranet isn't really shutting down their IRC service, rather it's just changing hands.
Unfortunately we weren't able to transfer nickname and channel registrations, so please re-register if you've come from Umbranet; we sincerely apologise for this. If you need any help simply join #help and ask one of the operators.
Welcome to Slacknet!
