How to contact Archangel Michael?

First off, Hi I'm new to the site. Second off, how are all of these people claiming to meet Archangel Michael able to do so? How do you contact an Archangel? I've always wanted to but have been unsuccessful. I may just be unlucky. I've never seen an angel in my life that I'm aware of. I think that it would kind of be useful to ask them questions about the things in life I don't understand. Also, what is this Archangel's personality like for those of you that have seen him?

I'm from a previously Christian background/upbringing so most of the information on this site is new to me, so if I don't understand what some of you are saying I apologize.
