I have create new page with my custom template. This page will be used by users to ask questions. The defult permalink to my page is http://www.mysite.com/?page_id=26.
This look ugly in address bar in the browser. I want it look pretty. For example just like in stackoverflow http://stackoverflow.com/questions/ask
Please advice where to look at.
Set your posts permalink to anything other than the default one (from Settings -> Permalinks).
Create a page named Questions, and then create a page Ask with the Question page as its parent.
