I'm no programmer so I have no idea how much effort this would take on the website but I was just thinking of something as simple as how when we put a cursor over someone's name and it brings up the menu of options, to have a big button that points to a FTS (which resides in the photo gallery). When it pulls the FTS up, it will be in a gallery view with your 3 prior FTS in a grid so you can see people's growth over the past year (if pictures were uploaded quarterly).
It's quick, easy, and it would encourage people to show how their tank's have morphed over the months/years. That's my 2 cents... what did I win Mike?
