Well, the post makes sense to me. Every windows person knows that vista will try to mess up the scripts when UAC is on. That's what appdata's for, to hold things that we don't have permission to hold in program files. However, it doesn't seem to apply completely here, as the files still remain in app data, but that's usually the case. Since the post makes sense, it may or may not be a bot. If it was a bot, surely it would have posted at least a few times, wouldn't it?
On the other hand, the name sounds somewhat bot like, but then again, with so many people using numbers, and with overal memory of humanity improving, I guess memorizing 4 digits isn't too hard!
And seeing he/she has only one post, they may not have commented because they may not have been on the Glest Board.
Of course, he/she may be a bot, or may not.
Wait, I just noticed he/she has an email adress, so why don't you ask? The adress looks legit, but hard to say, seeing spammers these days...
