I'll check with Adam and Aric why this wasn't fixed already, should have been done a couple months ago.
Check your spam folder.
Yeah, yeah. Typical response: 'the problem is on your end'. Dude, about 14,254 people had the same issue for months - now you want to blame me for not knowing how to use a spam folder. Maybe the issue is on the server? Did you consider that? Duh!
Let's face it - the Mastercoin forum is totally mismanaged and as a result nobody will visit. The posts are quickly stale and the conversations are totally dead. New participants are blocked from joining - in the name of 'security'. We wouldn't want any hackers to spread bad opinions - we need top security with e-mail background checks and high level encrypted passwords. You've locked the thing down so tight - nobody will join. Good one.
