Can I be a member but stop the magazine?

Hi,

I've been a member of the RSPB for 40 years because I want to support the cause,  however I never read the magazine because I just don't find it interesting. Is there anyway I can stop it being sent? It's not good for the environment for it to be printed, packaged and posted to me when all I do is put it straight into recycling.

Thanks for any help

Colin
