That's funny, because I felt it was necessary. Especially when your post wasn't there when I posted..Which is why I corrected myself thus making your post....unnecessary.
I'm not sure what to tell you. If you were bothered.. Post good, accurate info...the first time and there won't be any need to correct it?
Stop trusting press releases and do your own research. Done get suckered in when these companies shout..."New!New!" That also works. But, if you post incorrect info, expect and hope someone corrects it. This isn't facebook.
