I want to use WP to create a membership site. I've done that before with restricted pages, but all that does is set some pages invisible until a member logs in, then all members can see that page. I want to do something a little different. I want to have a user login and have a private page that ONLY THEY can see, and not other members. AND, I want them to be able to input data into it. Any suggestions?
Not sure but it sounds like your answer is probably with Buddypress and some kind of member privacy plug in. Not sure if they get their own page, but I think it is possible to make their profiles private. There are also plug ins to add fucntionality to profiles. Not sure what you want to use it for so I can't really recommend anything specific.
