Misc PHP for website

Misc development for Gaming Website. I need some misc work for my gaming website, specifically 10 small changes. Things that need to be done: - Only show social buttons if the user has made a link for it (3 in profile page) - Require http:// for social links and for video links in leaderboard submissions - Lower text opacity or change text to dimmer color of unverfied times to show it is not currently a legitimate time - Change [login to view URL] to profile/[username] for easy linking - Display unverified times in moderator dashboard on all profile pages rather than just your account page - Display moderator icon to regular users (only mods can currently see this) - Take out the "rank" section for unverified times and replace with "Player" so moderators can see who submitted the times - Require a valid email for [login to view URL] (users can just put "test"), disallow same email used twice - Display a 404 for profile usernames that don't exist (example: profile/thisisafakeuser displays a fake profile with registration date of 1970) - Limit number of personal bests on profile page to 10 entries to prevent long profile pages
