Well this may not be the best advice but I have had to perform in front of a crowd on several occasions. My method of getting over stage fear orignally was to have a drink, which calmed my nerves but soon i realised this wasn't healthy. Then a friend of mine said to me one day "When you are in the crowd watching someone, what are you thinking?" And what i think is, if i'm sititng there watching someone who is uncomfortable, I'll feel uncomfortable. It's a mirror effect in a way, give off good vibes to recieve good vibes back.

So next time you have to get up on a stage, or make a speech to a group of people, relax, smile and put yourself in the crowd and watch yourself.

Enjoy it

 HI, don't worry, it's not just you. Everyone more or less has stage fear. What you need to do is calm down by thinking all the audience as your friends or families, and don't look at them directly and put your eyes beyond them (though good speeches require eye contacts with audince), then you will be fine.
Be confident and think yourself awsome!

 This is what a friend of mine told me to do when your on stage looking out at everyone imagine that everyone is either naked or dressed like clowns it might make you laugh but after a couple minutes it might work but don't go on stage and start laughing just think that they are either naked or dressed like clowns or even rabbits. I had the same problem and it helped me big time I like to get on stage and sing but I was always soooo scared of what they may think or how stupid i might sound but it worked. Good Luck !!!!!

 Stand in front of a mirror and start talking. Do it daily, that gives you a lot of confidence to overcome stage fear.

 HI, Imagine that the PERSONS WHOM U r FACEing are not aware of any thing related to ur topic and they even dont interrupt u in between ur speech.Take three times large breath ,recollect ur previous successes which makes ur heart beatings and nerves relaxed.So go ahead and have a superb and relaxed seminar ...all the BEST

 I have learned the only way to overcome stage fright is by facing your fear head on. The more you do it, the less it bothers you. Also, I deliberately try not to think about it ahead of time. We psych ourselves on by dwelling on it and worrying about possible outcomes. I fake confidence. I convince myself and others that I am perfectly comfortable. You would be surprised it actually works. I am on stage weekly... trust me. Fake it till you make it!

 Everything above is great advice. The more you do something, the more comfortable you will become. If you have to do this a lot and still find yourself having trouble, you might consider taking a class. Acting classes can help, even if you are not an actor. Improvisational classes are especially helpful as they teach you to rely on yourself and your own resources. Best wishes!

 (I am in theatre) Make sure you are well prepared, do it in front of friends and family, if you are physically going on stage, walk on it a few times, look at the size of the hall in front of you. Try to make peace with your surroundings.

Then when the time comes to for example speak, make sure you have a single concentration point example a light on the roof / the blank wall in the back of the hall.

Don't look at the people straight on, it will make you more nervous.
Stand in a comfortable position. Hands to your side if not holding notes / hold your notes with both hands, be careful not to clench onto them.
Breath deeply before you start.
Good luck!

 Just imagine everyone without anything on .If you can see them bare,then it shows that you are on the same level ,all the same as you.

 Don't think so much about it before you go out or you will freak yourself out. While you are up their look over the audience not at them. Know what you need to say and play a little game of pretend, pretend that they are not even there. Its mind over matter. These are the things I do when speaking in front of a crowd, I don't mind one bit to speak in front of a crowd, and I am a shy person, so try out those steps. - mind over matte-r

 I believe that the first step is to face your fear i find it harder to give a speech in front of a few people than a 100. If you could practice giving speeches in front of your friends or family only then would you feel comfortable in front of a crowd.
