Re: What's happened to Shudokan?
at the moment shudokan uk is going strong there are dojo's in nottingham(2), lincoln(2), york, preston, oxford and devon(2). there is strong dojo's in poland as well. there are websites for most of these and you should find the link from the nottingham dojo.
as for the sensei "name" sensei thing, who cares who does what, it is their choice and leave it to them.
