3. Getting the Cool Hopper from the Snowman challange

That's strange, as its description says "complete a coding challenge". Try checking for new avatars and badges (in profile under badge counts). If that doesn't work, you can send a support request.

I completely agree. It's confusing, and when an error that drastic is made (so that half of the calculation is completely wrong), a correction box doesn't suffice.

3. Too many post in a short amount of time

Never experienced this before, probably because I've only been on the community for a short amount of time, but I can appreciate how it must be annoying for people who help a lot.
