.. And really, why make a section and put every map there?
People do in fact learn from other maps. It's how I learned to make maps in the first place.
And, uh, there is a good (in fact, very large) number of maps that are protected on this site.
I dunno if I got what you are poking at there. Maybe you are saying protected maps are easy enough to unprotect that it's like they are unprotected?
Everymap is like you say "unprotected" although that's a very lame word. I would say a better word is open source.
And no, it is impossible to learn from a map, you probably can imitate a map, not like it is worth it against real learning. That's something you can only get after experimentation and stuff like that.
Actually back when I was teh noobie of mapmaking, I opened up Dodgeball to learn about variables and many other things. That was one of my first delves into triggering, and now I am quite good at it. I doubt without taking a peek at that map, I woulda been lost for a reeeeal long time. --donut3.5--
I don't see a problem with a listing of unprotected/protected maps, like the DC. I don't think it would really "support" map stealing. If anyone wants to "steal" a map, he'll do it, with or without that function.
Nevertheless, I don't really see the need for such a function because you're already able to see which maps are protected or not (although it's not in a list). And if you really want to learn from maps, open Blizzard's Demo Campaign. You even have some description in it.
