I'm guessing the old thread was deleted due to a complaint from Rexair, since the information about the SRX is not yet public and it being posted on a public forum they probably threatened to sue the webmaster for it.
No that isn't the reason at all. A few members had posted things in it that they regretted posting and asked me to delete that thread. If I was contacted by Rexair and they asked me to delete it I certainly would have out of respect for the company's private information, however this wasn't the case. That actually happened once on automaticwasher by Speed Queen and once they contacted me I immediately deleted the thread as it had pictures of a charts that were confidential that someone had got from an employee at SQ. There wasn't a threat of a law suit by SQ, they simply asked out of respect of their privacy that I remove that information. I was happy to oblige.
I felt really torn as to what to do about that previous thread, and I felt bad about having to delete it for reasons that shouldn't have happened in the first place. So feel free to re-create it here, I've already asked those involved that if they aren't comfortable with the thread to not post in it.
