Having trouble creating a "clean-up" event...need help!

I own a dive center in the Florida Keys and want to put together a reef clean up event.  But I can't seem to find where you create this in Project Aware?  We have a tremendous amount of monofilament here, being the fishing capital of the world?" , and I want to rid the reefs of some of it, among other trash...any help with this site would be appreciative.
