"Devolution" is a good idea; though with care taken to make sure links are
strong and it is not seen as a "division" but as a recognition of
"you're
much better placed to organise this area of our outreach".
"Wikimedia in Scotland" is a great idea for focusing the brand.
There is no rule that says we have to use a single Wikimedia UK brand, and
in the current climate (especially in Scotland) companies are now quite
successfully leveraging a Scots targeted sub-brand. If this makes things
more palatable north of the border - lets do it :)
