Read the Guidelines, John! Or here:
Flaming
Flames - posts that are excessively abusive, attacking, threatening, or aggressive in nature - are unacceptable and will be removed without warning.
Whilst debating and discussion is fine, we will not tolerate rudeness, insulting posts, personal attacks, troublemaking or purposeless inflammatory posts.
We reserve the right to remove or moderate without warning, any messages that use insulting, threatening, troublemaking, provoking or otherwise aggressive language, or any member who consistently behaves inappropriately. Our decision is final in these matters.
