Tinypass is the best way to charge for access to content on your WordPress site.
If you have content that may be valuable, you don't have to give it away for free or accept pennies from ads. Now you can charge readers for the value they are getting from your site.
The Tinypass plugin allows you to copy the business model of the NYTimes and begin collecting subscriptions live on your site within a few minutes.
I heard about Tinypass from all the articles written about Andrew Sullivan going it alone.
And boy, this has been the best day of my business life so far in the content front since going online in 1998.
Seriously ... took like 10 minutes, and we are done!
Amazing extension if you are looking for a pay to view solution. Those guys really did a great job. The only thing i would wish for is an integrated affiliate system... but else than that its perfect.
Excellent support, simple implementation. Nothing else even comes close.
