There is no headquarters. There are no top dogs. There are various places around cyber space where different groups collect. Some sites may have top dogs for their activities and be completely unknown and unconnected to other sites. As you can see from the Venn diagram Jacky posted, this site, WWP, originally organized around chanology and since expanded to other initiatives, is but a small part of the anonymous world. If you have an idea, find the right forum here and start a thread about it. This place can be a little rough and tumble at times so please approach it with a thick skin. Oh, and welcome to the forum.
