I've seen quite a number of recommendations that appear to be reports of fraud, waste, and abuse. These include everything from inappropriate use of government vehicles to abuse of governement hiring practices. The GAO should receive a summary, especially of heavily trended topics that would appear to be fraud, waste, or abuse cases.
Submitters should also consider this. If it's that bad, don't just wait until Save Award time. Go to http://www.gao.gov/fraudnet/fraudnet.htm and let them know.
