Barrett is the guy who hosts the VPS Omni is hosted on, for anyone who doesn't know.
And Calcgames (calcg.org) founder.
That said I have an history of sending Netham45 PMs and never receiving a response back, so it's very possible that you replied to his e-mail(s) and he didn't notice. Or maybe the opposite happened, since Netham45 have just looked and he actually sent as many as he said.
@Netham45 about Windows the problem is that Micro$$$oft has a long history of producing buggy and bloated OSes that get more and more unstable as you fill them with random softwares and uninstall stuff. It was particularly bad around the Windows XP era, so while Windows may be easier to configure and use for most people, its unreliability at times could possibly explain why you have so much problems with it. When Omni was moved on Barrett's VPS and started having problems such as forcing you to change timestamp settings and other things on SMF, I thought the VPS was just misconfigured for SMF, but when I discovered that it ran IIS a few months ago, then I thought the issues were caused by IIS, directly or indirectly.
