I went back and looked. Since April 2014, the project has adde 64 people. What benefits would come from setting up different teams within such a small group?
Personally, I mention Wikitree often on my personal web page.
We are also quickly coming into the Celtic Faire/Festival season here in the Rocky Mountains, and I talk about Wikitree often while working my Clan's tent at numerous events. I don't see a team for the Festival workers, however, so don't forget a team for us!
