Did you make a thread about how to be a hacker, and subsequently realize that that does not belong here? Or maybe you imported drama from some other network. Maybe some idiot is posting about chem-trails in the Chanology section. Whatever the reason, if you want a thread deleted all you need to do is to click the little report button at the bottom of the post, and leave a short note for the mods explaining why you would like the post/thread deleted. That's it!
