Well if someone with your status posted it in each forum it would be ok?
It's a good cause after all!
even if we got a few more people involved, it all helps, just a post explaining what it's all about, a bit of information and a link, perhaps a dedicated email on the subject, I've lost several friends and relatives to cancer so I really feel strongly about this, If we can encourage more people to join in it can't be a bad thing!
