We should probably consider moving the WMUK stuff onto a seperate wiki/server at some point in the future, to avoid this issue (and similar/related issues) in the future.
Absolutely. I would suggest asking the WMF to host a wiki for us at uk.wikimedia.org (with wikimedia.org.uk redirecting to it) - I think we may need to wait until we actually have chapter status for that, though (anyone from WMF or ChapCom reading this, please feel free to clarify that!).
