Sorry for interrupting the discussion with an unrelated question regarding the masterchain.info-wallet (I didn't know where else to post; couldn't register at mastercointalk because never received the confirmation e-mail):
Mastercoin people don't want a community to develop. They've tried very hard to make their forum impossible to use and post in. They do everything possible to prevent others from talking about MSC. They even locked most threads on bitcointalk. They just don't want people to participate.
The confirmation e-mail problem has been going on for months. Don't expect to get any confirmation - they don't care what you have to say.
