This joomla! thing is pretty cool. You can build just about anything if you have time, creativity, and like working in community.  Working with high school students in a small town is pretty cool too.  They have tons of energy and the challenges go both ways. 

One of the tough parts about working with teens in a small town is that the really fun adventure stuff (rafting, camps, concerts) all cost money - and there aren't many people to sell candy bars to in a small town.  As a web guy and a youth pastor, I had to figure out a way to raise some funds in a non-traditional manner that would also let me track the progress per-student. Here are the tools and steps I used to create a donation solution for my church's youth group that allows users to donate and shop online in a way that helps our students.  If you need a fund-raiser for your church or school group, this could work for you.
