A few PHP and MySQL fixes for a good cause

We have a website [login to view URL] that will hopefully one day make a difference in the world. I can't launch it yet as it still has some work that needs doing to it. It's made in PHP with a MySQL database. These are a few things I need doing. All pretty easy for someone who knows how! Exchange links for Buttons "Add a problem/ share a problem" Buttons included Please make it so "user can edit a problem they've added" and "Admin can edit any problem" Admin or user can Mark a problem as "solved" On each category underneath it will list the solved problems for that category As admin I can verify a user but I want a "certified" badge to appear on their profile if I verify them and i want a list of certified users to be available i e "See all certified users" As admin can I be able to edit the "home description" and edit the text in "what is [login to view URL]" and an editable text box on “contact page”
