I mostly use SuperUser in read&comment mode only. I could comment, since I had 100+ reputation, thanks to my profile on StackOverflow. Recently I started a bounty on this question and I was stupid enough to grant all of my 100 reputation for it.

Now I cannot comment and I cannot even ask a question in Meta! I find this very annoying. It would be of much help, if I was warned about it when started the bounty. I did not even know such privileges exist!

What do you think about warnings on lost privileges, when you start a bounty?
