Who is CSO ?? Sorry Idon't know all the lingo Amber tiles gave me a sample of all my tiles. We still haven't chosen our feature tiles but i'm pretty sure you'd have to buy a sample of those if you wanted them.
the cso seems to be the contact once everything goes to head office - the cso rang me on thursday to say that everything had been sent to private certifier, and all the letters i've been getting are signed off by her - she seems very helpful
