I don't understand what you mean.
when i d/l the install it didn't work. php errors. then i found out i needed to get a host, and i chose to have WP host my blog.
Then, WP, gave me an address: thenameofmyblog.wordpress.com.
Then, i tried installing WP and it worked.
are you saying is the software is the same, but if your domain name or website address, or blog host, or whatever you want to call it i don't know the exact term, is wordpress.com, then you do not have access to files on wordpress' server like you would if you had your own web host, because your own web host would allow you to have access to your files so you can manipulate them for design purposes and etc.?
is this approximately what you're saying? also, do the .com and .org software look exactly the same and just some of the functions on the .com stuff won't work when tried by the user, or, do they actually look different?
Thanks!
is this kind of the jist of what you're saying?
