Although we are in the same boat sharing the same goal of fighting cancer, we are all very different, different in our perspectives, our value judgement, our interpretation to information around, and many more. As a webmaster of such an active site with thousands of visitors, Brian has every right to censor the content of messages especially on critical or sensitive issues. Somehow I think it may cause embarrassment or even ill feelling on the poster whose message is removed after being up for a while. I am not sure if it is technically possible that censorship can be done before any web link is posted and the poster can be informed privately if the message or link has to be deleted from the forum.That can make the poster feel more comfortable and respected.Just to add my two cents' worth.
