My scenario is this,
There are many categories on the site managed by the webmaster
one section is for users
* a user registers on the site (this is a chargeable option).
* They add a biography of themselves.
* They upload a photo of themselves.
* they can then update this biography at any time
* they can change the picture any time
* only registered users can see these biography's
How do I set up WP for this?
