Bob,
obviously, this is a great idea. I think we discussed it a few months ago, so I'm glad to see it come to frutition.
The idea is obviously to introduce people to the real features of the site.
But a lot of the times, people have no idea how cool and what all features our site ecompasses.
So, when we do enable Happy Hour, for all those people who are 'free subscribers', we should have a link at the top, in place of the banner, that says something to the tune of "Happy Hour in effect. All features are enabled..now here's what they are...go try them out" something that lets them know all the features they CAN use during happy hour, explanation, etc and can use all the time as a premium member.
I'm sure you've thought of that, but figured I'd bring it to the table.
Between the Jailhouse and Happy Hour, we might need to be careful we don't start turning up under 'rehab' and 'alcoholism' in a Google search. <g>
