BuddyPress.org

Sorry to jump in on what is apparently just a semantic issue, but I want to point out that BuddyPress is actually quite *secure*, taking advantage of a wide array of security features in WordPress intended to prevent against various kinds of mischief (SQL injection, XSS, CSRF, etc) and in some cases inventing its own. It is in the area of customizable, fine-grained *privacy* that BP is somewhat lacking at the moment.
