How do I Force the Use of Subdirectories in a Multisite Install?

Attn: Jack Kitterhing

Hi Jack, I'm still hoping you can get back to me; fine if you want to post here instead of an email.

I've found three links to be helpful (see below).

I did check with Timothy Bowers yesterday and he thinks all the instructions in the links checks out, but I just want to double-check with you and the rest of the community to see if there is anything else I should be aware of before I force the use of sub-directories... in particular, if there is anything new regarding this matter with the latest version of Wordpress 3.7*.

Thanks again to you and all for assistance.
