From the modder's code of conduct regarding ideas and copyright (copied from a similar discussion at bit-tech).
http://forums.bit-tech.net/showthrea...197582&page=4&
1) Don't copy another modder's ideas or mod unless you get permission.
2) Say thank you and give credit if you copy a mod
3) Mark your stuff if you want to tell another modder if and how they can copy it. (Langer suggested Creative commons at one point/Kayin CopyLeft)
4) The internet is full of monsters. Don't post it if you intend to profit from it or don't want others to profit from it
5) If you think you have been slighted, talk to the other modder. You likely have more in common than you realize.
Finally, when in doubt, refer to the Bindi Precept "Don't be dick." (Bindi©2010)
The idea was inspired by DB's mod. Mark should have given credit in his worklog so Kayin would have known. What's the big deal about printing a correction?
