I was referring to Yan's comment which was a sarcastic dig.
Fair enough, that one is more or less as you described.
I also don't think any of us are really able to guage this person's programming ability just based on a few things he's said
We're not really having to make any fine judgement calls here, we're talking chasms. He describes himself as a new noob, and says he knows the very basics of programming. That alone tells me he's not ready to make a gamemaker. Hell, I'm not sure I would be ready to make a gamemaker.
it's not up to us to decide for him whether he does the project or not. If there is harm done it's through his own decision.
If there's harm done - and it's because he asked for good advice and didn't get it - I'd disagree. If he gets good advice and ignores it, then that is entirely his own decision, as it should be.
Incidentally, I'd agree with you wholeheartedly if he replied that he intends to ignore the advice ( and he may do ) and then people came back to argue with him that he was wrong. If someone ignores your advice, it is - as you point out - their decision to make.
