Users are not permitted to register or choose a user name, real or otherwise, nor are they assigned one. Some users employ a code to identify themselves, called tripcodes or cap codes. 4chan content is organized into categories called boards. Some boards contain very offensive and graphic content.
While 4chan does not archive posts, some of the more popular posts will be aggregated at other sites, such as Reddit, chanarchive.org or Know Your Meme.
