I need someone to improve functional "Admin Panel" to multiple admin, manage memberships, content, users & profiles, and a manual method of maintaining multipul databases. The site must have an administrative panel that displays all users to me, (password protected) and will provide me with the ability to add/edit/delete/approve accounts, log in interviews and edit hiring progress.
