Paypal API Subscriptions is designed to allow your users to register on your blog and subscribe all at once. 
The Paypal API keeps them on your blog and means that you simply have to skin the WordPress Admin to suit your 
site theme. Because it is fully integrated with WordPress you can keep track of your users easily and effectively.
This plugin defaults to the Paypal Sandbox for test results so you can test it for yourself.
You really need SSL before you can begin to think of using it for real. Download Admin SSL here: <a href="http://www.kerrins.co.uk/blog/admin-ssl/" title="Admin SSL" rel="nofollow ugc">Admin SSL</a>.

Recurring PayPal Donations

Paypal changes something in how they process form submissions about two months ago.  I was working on a similar plugin called Custom Donations.  I was experiencing a problem where Paypal would say that the link was bad.  I was looking to see how this plugin handled that problem and found that it was also broken.

Broken after Paypal Changes

Accept PayPal subscription or recurring donation payment from your WordPress site easily.
