You can add your own projects to the site, which is a very easy procedure, and create an account to have your own profile, which is useful to merge all your contributions to various projects into a single person. I.e. if you have contributed to one of the registered projects and search for yourself, the web will return some hits; if you have an account, you can claim that you are that person and link your contributions to multiple projects into a single page.
Check out my account for an example :-)
