That's a good question. We were Mirage Online players. We were Player Worlds users. Who are we NOW? We are, like you, Mirage Source users. If you've read the history, you probably know how Mirage Source got here. We're taking that source code, and all of its users, and uniting them into a community.
The original release of Mirage Source from Mirage Universe was not supposed to make into a great big project or anything, as you can probably guess after reading the history. Originally founded by John Gunter (aka Granite), and now owned by Shannara, the rightful owner, this site was created to make a big project out of it, and a nice big community. We are the ones to bring the Source users together.
