Create a Joomla Template

1. I need an extra field called " Website" on my USER account details. 2. I have a responsive grid article display. I need a button next to "hits"(views number) at the bottom. When clicked it should open the article only on a popup and in the background it should open the website of that user/author in a new tab. If the visitor has already opened a certain author's article/website, it should not open the website again for that author if the visitor opens his any article again.
