I can not find what symbol I should put between I and m if I want to write 'I am'

Hello dear Torsten.
It is very good that you are trying to help us for learning English and pass exams. I am enjoying these courses, and its pleasure to grow up my scores by passing tests. I am very attentively waiting to your next mails. The only problem is to use the Forum. For example today I can not send mail to introduce my self. Now I am not sure I will send this mail. I can not find how to put my picture in forum. And finally I can not find what symbol I should put between “I” and “m” if I want to write “I am” shortly. I hope I were inderstandeble.

Sergey, good afternoon.

Try I'm = I am.
