===Welcome to the '''GoldSim Wiki'''!===

The GoldSim Wiki is the online user-supported resource database for [GoldSim| GoldSim], hosted by the GoldSim Technology Group (GTG). The purpose of the GoldSim Wiki is to provide modeling resources for GoldSim users.  Although GTG actively supports, contributes to, and moderates the Wiki, it is intended to provide a mechanism for users to share their knowledge and ideas with each other. Therefore, we strongly encourage everyone to participate.
