i'm sure someone will take it off me? but i could only send it to the UK (or maybe i will stretch to europe for a very good reason). sry but i'm not paying a lot on postage ie. to USA or beyond.
not decided how to give it away, hehe maybe if someone gives a really good reason, or someone who donates to NovaHQ, or something? suggestions welcome
