OK. When you say your host provides WP that is fine. But WP does not need access to any part of your server except your own web space. There is therefore nothing to prevent you installing Word Press in any directory in your domain. I am assuming you have ftp. You do not need to trouble the server admins at all. What you will need though is to be on a server that includes at least on mysql db in your account. As to Q2 all things to do with style are in the file wp-layout.css.You can download the css for any site you like (assuming the owner doesn’t mind ) and simply upload the file to the directory with the file named as wp-layout.css Worth keeping a copy of the original file of course in case it blows up. To alter the file if you need to I would strongly advise that you do not use the edit template function in wp admin which is for emergency use only when you are away from your own machine. Instead simply open your local copy in any text editor and have a good look at it. When you are ready – start hacking. Then ftp it to your server. Good Luck. Post again by all means.
Root, unfortunately not all if your reply is showing up in the field. It is, in a word, getting truncated.
BTW, pestering them is what a host’s tech support is for.
My post looks fine from here. But I am on Firefox. Performance in other browsers can be erratic.
mythusmage,
Most of the templates will have installation instructions with them.
mythusmage,
Download the version of wp you want and install it yourself.
