But PLEASE remember not everyone wants setlock. Please, please, PLEASE tag your setlock on tumblr, Twitter, etc. Be courteous to your fellow fans.
The Babes have some tips here. If you want to block or tag on tumblr, the Final Problem can tell you how. Tumblr also has a spoiler warning generator; how cool is that??
