How do you edit comic info on mangago?

I'd like to add some information to a manga, but can't find a way to edit a page. I read somewhere that you can either click some "white flag" on the comic's page or email the admin, but neither option seems to work: there's no flag anymore and the email is disabled. Soooo is there possibly some other secret way to do this?? There must be, right? ╥﹏╥
