ok, Jonathan and Eystein, Keith and I have said about as much as we can,
we are falling over each other trying to not to push our own work, its

just tell who what to do what.....

as for contrib. author, I still think it is a good idea to try to keep
the reviewers separate although now that I think of it I am not really
separate so maybe it is a moot point
