1. Be a fan of calculus.
2. Provide a (nick)name, a working email address (which can be hidden), and the country you live in.
3. A website is not needed. However, if you do submit one, it'd be appreciated if you link us back using a linking button, such as one provided on the Buttons page. If your website has questionable material (hateful, pornographic, etc), I will list your name and email (if you choose), but not the site.
4. If you want to change your information, use the Update form provided from a link on the Join form.
