You must be crazy
"The Pharmacist" didn't pay any 50 bitcoins to become "The Sceptical Chymist"
This is some kind of money scam. Some users change their nicknames for free, while others have to pay 50 bitcoins? Are you seriously kidding?
When I replied, I asked myself why this thread is self moderated. Now with your reply to me, plus your previous replies to others, and answers you received but did not read, you want to troll.
I don't feed the troll, so I quit this discussion.
