I was browsing through this NSF report on Dimensions of Biodiversity Projects 2010-2012, and I stumbled across this project which I had no idea even existed!
Upon further investigation, I discovered that this ciliates RCN has a portal website (including a document listing "Grand Challenges" in the study of ciliates). The inaugural meeting took place in September 2012 at NESCent, so it looks like the RCN is still in the early stages.
Frustratingly, the website doesn't seem to have been updated in quite a while (May 2012), so there isn't much new information about workshop outcomes or upcoming RCN activities. I'm excited to keep tabs on this new community - the discussions and outputs will be very relevant to high-throughput environmental sequencing approaches.
