Best way to solve this problem

[Zabulus]

My webpage pokerowned.com (You can use a demo login: DramaKing password: DramaKing1) needs an upgrade. My currently programmer and have hit a brick wall for ideas on how to best release our password.

I will explain:

We offer freerolls to players and show opted in members (Those who use enough points get access to the freerolls passwords). We show the users these passwords 60 seconds or LESS before the start of the freeroll.

What the problem is, within those 60 seconds, our users MUST refresh the webpage to see the password. This causes a ton of stress on our server and sometimes crashes our site.

What is need:

A better password release system.

We need some way that the users who are opted in will see the password without having to refresh the site (And the server doesn't get hammered also).

We thought about a 'pop up' private msg that happens, or something else. We're stuck..

What is the best way to accomplish this without hammering the server?
