I have installed one wordpress system in my website http://www.abc.com. Copied all WP files folders in domains root and installed it and it is running.
Now I want to install a separate wordpress system e.g I want to install a blog in my site , and I want it in a subfolder http://www.abc.com/newwp/
Shall I install two separate wp systems. Or shall I follow multisite installer or 2 separate normal wp installation?
When I need a multisite, do I need multisite ?
