Buying shares ?

Hi there, im 18 years old and im interested in buying shares and learning how it works, can somebody give me some advice how it works and what shares should i buy ?
Answer
Stick to the blue chip shares. you can lose so much money on aim and other shares. companies like bg...powergen...etc are safer. you can buy and sell shares with computershare on tel 0870 707 1411. you can also go to some branches of barclays banks which might be a better idea for you as you can discuss things with them. you will obviously be charged a fee which is usually about £15...might be higher now as i have stopped doing shares and passed mine on to my kidren.study the shares in the papers or watch them on bloomberg (tv)for a while before you decide on buying any share.
