This guy may be angry and obnoxious, BUT...he's in the right.
He got the wrong plane. Nitroplanes made the mistake. Not him.
He did not get any result until he came HERE. He complained all over the web, but this is the only place he got any result.
That has to improve. I love Nitroplanes, but they have to do better that way.
Now he is getting fixed up, but if he got proper CS in the first place, he would not have left nasty posts all over the web, even on Nitroplanes own blog. That's an expensive way to do business, and Nitro needs to do better that way. It should not be that the only place you can get a result is here.
So, while this guy may indeed be a jerk, he's still in the right, and he's frustrated, and you can't really blame him too much.
I'm just glad he found the right place, and is being taken care of.
