Teen tech Talent bank

My sister, Lynn, is suggesting a new kind of youth group project. She was listening to an elderly woman' s frustration with some computer problem. My sister suggested that she just needed to find a teenager, who could no doubt solve the problem without any trouble. When my mother in Thief River Falls needs something done on her cell phone she has been known to simply walk across the alley of her backyard, out into the park , and approach any teenagers who might be there, asking if they could do what she needs to have done.
So here is the idea. Remember when youth groups used to do service projects for church members such as rake leaves or put up Christmas lights? ( I remember doing that) Maybe this could be updated into a different kind of talent exchange. Today typical tech savvy teens could be available to set up computers, enter new software, change email accounts, enter telephone numbers or set up speed dials on cell phones In turn they might come home with home baked goodies. Anybody out there all ready doing this , a teen tech talent bank?
