Thx Tim for validating this torrc configuration, before deploying it. Ok, I'll remove those 2 lines. (but it can be helpful for Tor network on fast bridges ?)
About stats, I see Atlas and Globe can give informations when you know the Bridge's name... I was thinking they were only useful for relays/exits... Nice!

You really don't want these two lines, they make your relay try to be an authoritative directory.
