I got that impression too, and there was a reason why I tended to believe what he posted. That said, frankly I've seen other people with similar things in their first post who ended up NOT being accurate. What JimDahl said is quite true. In a forum situation, there's no way to prove your credibility until your information is confirmed by a source considered credible by the general populace. Once you're information proves accurate, your credibility raises substantially.
In a sense you're victim of other crackpots who post similar type things with no actual information. In the end the truth will prove out. Might as well wait it out, and accept the apologies at that time. It's better than running around screaming and telling people they have to believe you.
