I have managed to mess some things up. Or at least thoroughly confused myself, in my own ignorance.
The WordPress installation on my site was installed under user tspnyc.
But when I found out that if I use that username to actually manage and post on my site, the metadata will show everyone that tspnyc made the posts, I decided not to use that name. That acronym is well known in certain circles and I would prefer my onemanz.com blogging to at least have the appearance of being more low key, if not anonymous.
I created a user in my WordPress dashboard called oneman and I deleted all other users. So the Admin and only user created for the WordPress portion of my site is called "oneman."
I also created an ftp user account in Dreamhost called ftp4omz, but now I see it matters a great deal what user uploads things to FTP.
I had wanted to use that as my primary ftp account and not use tspnyc.
But my WordPress install is under tspnyc, which caused all the hoopla of my not seeing onemanz.com folder in the foot of the FTP tree. I was logging in with ftp4omz, not tspnyc.
Two issues arise here.
is there any reason why I cannot continue with oneman as my WordPress site admin account, while retaining a separate Admin name for the Dreamhost control panel and FTP loading? Will there be issues when it comes to accessing subdirectories, subdomains, etc?
Is there any reason I need to use the original tspnyc user at all? Does it have privileges other users do not have? Can I change either the name of this main account to oneman, or create a oneman ftp user to be the main administrator of my Dreamhost and WordPress site, both?
I would be happy to uninstall and clear my server and reinstall WordPress in the new oneman user directory, if that makes sense. The site is only made up of test gargage right now.
Or is there really no connection between the WordPress site admin and the FTP admin, so it doesn't matter if I use tspnyc for all FTP and Dreamhost realted things, it will not affect what user oneman does when making the actual blog sites(?)
