What are the simple ways  to gain more self confidence in public speaking?

My answer to What are the simple ways  to gain more self confidence in public speaking? on Quora

Be confident that you understand your subject matter. Practice, out loud, in private, as many times as possible. Have notes in your pocket so you know you can fall back on them if you really need to (you probably won’t, but I find knowing they are there helps with nerves). Then get as much speaking experience as you can. BarCamps / Unconferences are a useful place to get started.

Many people recommend Toastmasters—I’ve not tried it myself, but it has a great reputation.
