Check script for infiltration (injections etc.) ::: Please DON'T send me canned offer that majority send as soon the project is posted. It's unprofessional and lazy way to introducing your self Make sure you read my project. Think about it first, then answer! Make sure you have the right skill as well.

You may reject the work after you check the site backend and dbase (no problem) Same script as: [login to view URL] If we click I will have more work and other assignments.
