Finally all you have to do is activate your server
Depending on the channel rules, you have a few options on how you want it activating:
On -> This means that the server will respond to !list and also the file server will advertise in channel if have have set an ad delay in basic settings.
Silent with list -> This option means that the server will respond to !list but won't advertise in the channel (Most channels like you to have your server on this option)
Totally Silent -> Doesn't respond to !list and doesn't advertise
Send Only -> As totally silent and also no one can access your server, but it will send any current sends and queues you have
Off -> Off :P
