1) Usergroup Manager > Edit Administrators > Username HTML Markup

The first field is the opening tag. The second field is the closing tag. These tags will be inserted around the user's username like this:

[opening tag]username[closing tag]

Some HTML tags you might want to use here include:

<span style="font-weight: bold;">username</span> = username
<span style="font-style: italic;">username</span> = username
<span style="text-decoration: underline;">username</span> = username
<span style="color: red;">username</span> = username
<span style="font: 20px verdana;">username</span> = username

You can also do combinations by using more than one attribute in the style property:

<span style="font: 20px verdana; color: red;">username</span> = username

2) Read up on User Ranks in the manual (link in my sig)

3) Edit the header template. You should post that part of your template if you need help.

4) Upload them for what? To use on your site for your style? Any ftp client should do.
