Sounds like homework! Use Google and do your own legwork.

I hope for you that you’re just kidding.
if it sounds like homework to you, that means you misconcieve not only the intent of my question, also the reason for this site.
Why should you feel obliged to accomplish this ‘homework’ if it were such..?
I know my authors and artists, when sharing with others, one way to discover who to exchange info with and what to exchange, is to begin with a question. when the answer comes, so does the conversation.
Good luck for your understanding things.
cheers

@Cardinal, by the way.
