 * Represents registration packets. An empty GET query will cause the server to return information

 * when creating a new account. The standard account attributes are as follows:
 * <ul>
 *      <li>name -- the user's name.
 *      <li>first -- the user's first name.
 *      <li>last -- the user's last name.
 *      <li>email -- the user's email address.
 *      <li>city -- the user's city.
 *      <li>state -- the user's state.
 *      <li>zip -- the user's ZIP code.
 *      <li>phone -- the user's phone number.
 *      <li>url -- the user's website.
 *      <li>date -- the date the registration took place.
 *      <li>misc -- other miscellaneous information to associate with the account.
 *      <li>text -- textual information to associate with the account.
 *      <li>remove -- empty flag to remove account.
 * </ul>
