To avoid saying and discussion things that could be in violation of Forum Rule #1,
if challenged, we will need to be able to say that what we said can be documented, if necessary, at the appropriate time.
I am not saying that we must produce documentation at the time we say it, but,
if challenged, that we can provide documentation at the appropriate time.
I am not saying that we need to be able to provide documentation on everything we say, as long as we clearly contain "in my opinion" in your statement.
This is how Forum Rule #1 reads:
1 - You agree not to post any material which is knowingly false, defamatory, inaccurate, abusive, vulgar, hateful, harassing, obscene, profane, sexually oriented, threatening, invasive of a person's privacy, adult material, or otherwise in violation of any International or United States Federal law.
Fee free to discuss this here.
