Fix up website using GAF and EUFreelance API

Hi there, I want my site [login to view URL] to have the php code updated to make use of the GAF API (it currently scrapes data and is broken). It needs to fetch from both GAF and EUFreelance.com. I'd like the categories also on the front page updated and to dynamically do so by checking the front page of GAF periodically in a cron job. The existing code is all written in PHP. Also: * The email alert function needs to be implement * Addthis should be added to every page * The "email this" function needs to work properly * User input needs to be checked to stop injection or cross site scripting attacks thanks!
