RSPB campaigns

Hi all.

I keep getting my regular RSPB email updates and even though I've moved back to New Zealand now I still really want to be able to sign the campaign letters online. However it seems that it's only for UK residents..Is there no option to apply international pressure to the British government? For example, the latest one is regarding encouraging and assisting farmers to create wildlife friendly farms, which I would love to add my voice to!

Does anyone know how I can still be involved in this?

Thanks :-)
