I set up a website and training with the mane “The Art of Making Friends”
www dot artofmakingfriends dot org
I am also thinking of selling DVD under the same name.

It turned out that it has the same as a book (not mine of course):
[unfortunately I can't publish link here but you can find it on Amazon]

1) Would it be a problem for me?

2) As an alternative.. what if I select a trivial name like “How to male friends” that anyone can use ?

Thank you
