Some other sedgeheads and me have worked together to create an email system so we can email each other about sedges. I'm at the core of the group, and manage the email for the group. Not many people are specialists in sedges, and I'm the world's expert on the genus Carex in Arkansas! That's not hard to do. It is like being the world's expert on sedges in Jiangsu Province. If there's only one person studying something in one province, they are the best. Here's a few photos I posted to the group today.
