Thanks to everyone for their responses. Several people directed me to the specific project I was looking for: http://www.adventureandscience.org/about-us.html
For search geeks, apparently the key phrase for searching the ecolog archives was "willing to collect" (not "travel" + "collect" + "volunteer", or other similar terms I was using). Feel free to keep sending me messages about your favorite other Citizen Science projects. Because some people have expressed an interest, I will send out my compiled list of projects in a few weeks when I am done. Thanks, Marta Shocket Indiana University
