I've currently got WordPress installed in a subdirectory, so it is currently accessed via http://mydomain.com/wp. I'd like to reset things so it can be hit directly via http://mydomain.com. I've been looking at the instructions at
As far as I can tell, the second two sections ("Using a pre-existing subdirectory install", and "Pointing your home site's URL to a subdirectory") are two alternative approaches to solving the same problem, with the latter approach appearing to be dramatically simpler. So why the former? This page is missing an explanation of the relative advantages and disadvantages of each of these two approaches. What should I use to guide my choice of which of these two methods to use?
Thanks for the info, much appreciated.
