Sean K. Elders - Elders Academy of Martial Arts

Does anyone know or have you trained with Sean Elders? He lists Full Instructor creditials for several martial arts under Paul Vunak, and John Lopez. I have read on the Bullshido forum that full instructor under John Lopez could be obtained by purchasing his training DVDs and hands on training was not required. I'm not sure what Paul Vunak requires for full instructor. I don't have 5 posts to the the Bullshido site so I can't include the link to Sean's website....authenticjkd

Thanks in advance, and please forgive my noobiness, if this has been asked before.
