Make every effort to contact an author if you want to use their work and their permission is required, preferably by e-mail - if you receive no reply, then try again in case your mail never reached it's destination, and failing that perhaps post a private message to the developer on one of the popular Western BVE forums, or ask for the help of another developer who could aid in contacting the original author. If after exhausting these options, you still can't contact the author, then ensure that all credits are properly written and included in your add-on. If you can demonstrate that you made every effort to ask permission, should the original author notice their work used without giving you the go-ahead, they probably won't mind so long as you tried your best to contact them before hand. This advice may not apply to material originally sourced outside the BVE community however!
