Orespawn
OreSpawn and everything in it is copyrighted to TheyCallMeDanger (Richard H. Clark) and Megan Lorraine Clark, 2012-2015.
In plain English: For the most part, you have permission to use, abuse, review, modpack, redistribute, and generally run amok and have fun with the OreSpawn mod. The one caveat is that we ask you to give credit to TheyCallMeDanger and post a link back to OreSpawn.com. Pretty simple. If you happen to be making oodles of cash from using this mod in some way, then we ask that you at least think about buying a few T-shirts! Maybe give them away as prizes? Thousands of hours of work has gone into this mod, and the people involved in creating it wouldn't mind a little pocket change now and then. Thanks!
