I recently referred someone else to the StackExchange network. However, I was quickly pointed to a pretty embarrassing problem:
The new account started with one reputation. But with just one reputation, one is unable to upvote, unable to comment, unable to answer a question, and not even able to put this question on meta.
Someone please advise: how do you start participating in Stack Exchange if you don't have a question? Do you really have to make something up?
