Officially no one is a 405th member, not even Adam. The charter doesn't exist just like the 405th. We can post as many little logos and stamp ourselves as much as we want, until we get a charter and the approval from Bungie, we technically don't exist.
Hmmm ... Maybe we should contact Bungie on this matter. I wouldn't mind doing it, since I have a bit of a why with people. Adam should probably do it, though. VIVA LA 405TH!!!
