No, it hasn't.
I agree partially with Ryu. I disagree with the example Ryu gave, as it was too similar. Some, tutorials are considered "too simple". I doubt the average new user knew how to do that. I sure didn't in my first week. I feel that "too simple" is very opinion based--not everything has to be hard and confusing. And different versions shouldn't be locked either. New ways to do things should be appreciated. Some are locked apparently because...they don't look good to some people...? It always puzzled me why that one was locked.
Also, I feel the following were unjustly locked:
viewtopic.php?f=15&t=23750 (a different method)
viewtopic.php?f=15&t=23558 (Apparently this was locked for no reason...except that it was an image? :? )
viewtopic.php?f=15&t=23318
viewtopic.php?f=15&t=23256 (just because it has been done before, doesn't mean it's not helpful!)
viewtopic.php?f=15&t=21572 (Locked...because someone necroposted?)
Sorry, it doesn't come out like that.
This I don't understand; many people lurk for several months, and when they join, they can be just as much experienced as any other poster. True, stereotypically first post tutorials aren't that good, but you can't say that universally.
All I'm saying is, the second to last quote should be upheld; currently it seems everyone has forgotten.
