Hi!
Sorry but Me as web user i dont want to share my private things at strange sites. Gmail and other sites knows me better than myself. You may consider a nice privacy policy at Your site too but i dont have good feelings about this. Today web privacy is treasure!
Its more of a leaning diary for notes, rather than personal data. it is to be add to a medical quiz site. Is it possible to have a page of items that only that user and the administrator/teacher can see.
A blog that is only accessible to the creator and the administrators.
is it for a small group of set users, or anyone? you could set up group access rights, and only have a single user within the group, then from the frontend only that user can see their page
i like to modify things, and make them do unintended things
