I was wondering if I may have my rank back? No future mistakes like that.

Again, you aren't automatically entitled to a promotion. It will happen if you continue to demonstrate competence, and someone suggests that you be promoted (asking for a promotion does not increase your chance, in fact, it accomplishes the opposite). A good step towards that promotion would be to participate in a discussion or two, perhaps even from a few pages back.


Now that is one of those solutions that I never would have come up with on my own. Knowing the solution/solving the problem doesn't quite have the same appeal to me as solving a logic problem, or analyzing a problem with game theory.
