I have/am using wordpress.com to protect my content with a password. This is what I do:
I do to post, an intro and a continue. The intro is the teaser and the continue is locked with a password. To get the password they need to complete a form (aweber) that sends them the password. This creates my database.
I have now moved over to wordpress.org because I need more flexibility. But technical issues bog me down.
I want to make content available to people who I qualify.
They will get the content for free if they qualify.
I want show them a teaser but to read further they need to complete a form. I'll use the form to qualify them and if they qualify I can subscribe them to my blog.
It will be nice if the full article can be indexed by Google.
The password option as used with a intro post and a "continue" is ok but a real pain.
All I need is to protect a portion of the post or create a teaser for the post and lock the rest.
I tried http://fortes.com/2005/12/27/post-levels-10/ but there's no support and I get a 404 error when I use it.
Hope you were able to follow my ramblings.
