Hey Kim - my background is in grant writing and I worked A LOT with the CDC / HRSA for a variety of public health issues to win awards for cities, states, regional health entities and non-profits. I have several ideas for how this would work and have even been in touch with some grants trainers about using GovLoop as a pilot testing ground since we're on Ning. Basically, you could create a group here around a specific grant to learn how both the administering agency and the grantees would use it. If you get good adoption, build out a larger site...but I'd test here first so you can get a sense before investing in a full build. Let me know how I can help.
