Stolen from everybody, equally. :D
1. Create a graphic (200 x 200 max size) to represent your personal "candy". It should have your username on it, but otherwise can feature whatever you want. Make it something special since it's self-representative.
2. Make a post with the subject "trick or treat?". Put your "candy" somewhere in it, and be sure to repost these instructions.
3. Then, go around other people's LJs and reply to them with either "trick" or "treat." If you reply with "trick," they will give you an LJ/DW/Twitter/tumblr (Twitter works best!) dare that you have to perform before taking their candy. If you're too wimpy for that, simply say "treat" and take their candy.
4. List all your collected candies in your original "trick or treat?" post to show off your collection
My candy:
Candies I've got:

yuumei_nata: Every time you see a mention of an Eito member on your tlist, tweet "Call me maybe, Justin Bieber-oppa <3" (no need to spam, though, max once every 30 minutes~) for the next 48 hours
