I am a DJ who is temporarily in Japan, but I will be returning to Hong Kong in three weeks to live there. I should have events there very soon, and I would like to have an artist page to promote them on this site.  I can't find any information about it in this forum, and whenever I click the Help link it says there's an internal server error.

Send a message to admin. It might take a while though, they get many requests, I think. Anyways, you can still advertise your events. All your fans will see them.

Details and procedures for becoming an official artist are here:
