In Motherlode i notice that in lot's of add-ons there is a phrase says "Free for non commercial use" or "I authorize that this product may be distributed free of charge, and non-commercially". That's mean that i can use and motify some add-ons as i like it, right? For example i downloaded Bonandi and motified it orbiting around 61 UMa. I hope that this is not illegal.
Of course for personal use only.
