Are you referring to a sect, or type, of Buddhism or an organization?
As for sect or type of Buddhism, I’d consider myself Theravadin with some Soto Zen thrown in. A lot of what I know of Buddhism I’ve learned through talks by Gil Fronsdal, Jack Kornfield and many other speakers that have been on Zencast. The rest has been through reading web articles, books, magazines and my own experience.
If you’re asking about organization, I don’t belong to an organization. I live in the midwest and living here there are very few sanghas that I can regularly visit.
