Credentials plugin

Hello

Case: I’m looking for a wordpress plugin or workaround to do the following:

– people get credentials for the site
– after loggin in, a few pages are visible to them
– one or more pages are personal for them, and only for them… and are editable for them…

Story: people login to write down some wishes for their funeral, ideas, links to music, some texts and they can always edit this page and add some information… to their personal page… group pages with ideas from the person who owns the site are visible for the group of ‘clients’…

I tried this with the plugin wp-clients… superb plugin but I don’t get the possibility to edit the personal page with this plugin…

Anybody some ideas how to do this?
Anybody some ideas how to expande the possiblities of wp-client plugin???

Thanks a lot…

Greetings
