[QUOTE=Blowfish;186315]Ok, after two fails, I tried to make an ET map, but now with some good help.
Question : Can I use anything from the basic ET maps into my own maps ? Ofc, maps made by others, first ask permission. [/QUOTE]
Taking stuff from the 6 standard maps is widely considered acceptable, but be careful that it doesn’t look too much like a standard map, that might cause “damage” to the whole community (ppl stop downloading custom maps).
And ofc as you said, taking stuff from custom maps, ask for permission, then give credit in the readme.
