Depending on how your site has been set up, there are three common ways to log into a Caravel site:
1) A login block. In this situation, the login form is embedded right in the layout. Just enter your userID and password and click the Login button
2) A login button. Particularly on older sites, there may be a login button in the lower right corner of the screen. Click it to log in.
3) A login page. On more recent Caravel installations, you can type /login.php at the end of any page URL and you'll get a login page.
Tip: When you use a Login block, you have the option of redirecting the user to another page when they log in. This can be handy for directing them to Members page with links to members only content.
