How do I change the text that's to the right of the entrant form?

You can show any html to the right of the registration form by adding a line to your entrythingy code like this:

w_['register_right']="Put any html here. Already have a login? <a href='javascript:displayLogin(false)'>Login here</a>";

Put it under the line that starts with sitecode=. Make sure it's all on one line - ie no line breaks. Also make sure you include the login link so that administrators, jurors and registered entrants can login. The login link looks like this:

<a href='javascript:displayLogin(false)'>Login here</a>
