The short version is that official channels (also known as primary channels) are named starting with one #, unofficial (topical or about channels) start with ##. If your channel is not an official one, please use ## at the start of the channel name, or you may be asked to move. Getting it right at the beginning is a lot easier, for you and for us. There is more information on this policy [here](http://freenode.net/policy.shtml#channelnaming).
