I am seeking to have a website service that offers my visitors to create a personal profile/vcard very similar to the site about.me where you simply fill in some blanks and it create a page for you on my name with the username/url you have chosen (e.g. example.com/username) however I have no idea what this type of software/script/coding is considered or referred to.

What I am seeking is very simple, all profiles will maintain the same exact theme and colors.

This is my first post, I apologize if I have asked this on the wrong thread but I do know for a fact that I want the website to be responsive and html5 - if any one can help guide me to what I should look into to get this done I would really appreciate it.
