Don't be such a miserable old sod, Earthstepper! :-)
It has to be done by concensus, consensus, conscenus (sp?) - bugger, can't spell!!!! We all have to agree and be happy with it - this is an autonomous collective, not a hierarchy. I firmly believe that once we have a name and strap that we all sign up to, (even if we don't necessarily agree with the nomenclature precisely) we can begin our quest to be archaeo-action heroes (and heroines) and begin the lobbying/letter-writing/campaigning in earnest.
But it would be easier to do this kind of decision-thing in, for example, a public house...
On a message board it takes a little longer.
