Skippy,Daveboat and others.
As I have already published my email on this site recruiting people for an East London Off-Grid Practical group and not exactly been swamped Please use my email as a contact arena,
Email me at peasant(dot)urban(at sign)googlemail(dot)com
Let me know who you would like to contact, if I receive an email from both people I will put them in contact with each other.
Hope this helps until a better solution is found.
