Answer 1

On any profile that you manage (or are on the trusted list) or that has open privacy you should see an "Edit" tab.  Click that and you will be able to add or change the information and text.  Here's a link to the Help page with more detailed information: Help:Edit-Profile Page (wikitree.com)
