Just to let you know I am on the edge of the bloody world in west Wales (next stop Venezuela!) on a field trip and cannot access my inbox. You sent me a PM but the wifi here forbids me from opening it. If anything important please send me a text! BTW I thought the one saving grace here is the bar (nearest pub is 30 minutes away and no transport) but they served wine that can only be described as sauvignon bleugh so I am not a happy bunny!
