Thanks for help!
But your solution is to create a "static" page.
My task is to have a User template that it runs when you click on a user name and brings you to a page where you can find all the author's posts.
E.g: When you click on a category the url changes in www.mydomain.com/categories/<category-slug> and brings you to a page listing all the posts in a that category.
I want to do the same thing but with the Users, any ideas?
