phpMyDataGrid is Open Source released under the BSD License, and we need your help if you like this script and think to use it 
please make a donation. Our goal is To buy a house for 2 little childrens, so we need to collect USD 20.000 by receiving 4.000 
donations of USD 5 each, (If you think you can do a higher donation, don't think twice, just do it ;-) if you compare, you can 
find commercial versions with less features than phpMyDataGrid with prices higher than USD499.  So, just to make a donation is 
a cheap. 

Please remember donating is one way to show your support, copy and paste in your internet browser the following link to make your donation
