I found an interesting Proposal, and I'd like to answer on the questions or vote the answers.
However, I have only one reputation, and I need at least five rep points to make an answer.
Is creating new questions the only way to gain enough reputation points to be able to start answering? Do I need to push the "Commit!"-button before I can do anything on a given Proposal?
(I waded through the Area 51 FAQ, but I didn't catch anything on my eye which would have answered my question)
