I don't want to change the homepage into a static page and then add a blog page as the post page in my dashboard. I just want a separate blog in the same domain.
1) http://www.2createawebsite.com/ and http://blog.2createawebsite.com/ respectively
2) https://teamtreehouse.com/ and Treehouse Blog - Learn to code and change your life! respectively
Can this be done in my single WordPress install?
