Hiding "most reads" etc

Yes, it is possible, but it's kind of tricky.

You are not able to hide the mostread page, afaik, but you can move the content of this page to another, non public one:

• Open the skin of the mostread-page: http://your_blog.antville.org/skins/edit?proto=site&name=mostread
• Cut the whole content, but leave a space character in the input form
• Open the skin of another page, which is not visible for users, e.g. the member page: http://your_blog.antville.org/skins/edit?proto=membermgr&name=main
• Paste the content of the mostread page at top of the form (without overwriting the existing text, of course)

So visitors can still open the (now empty) mostread page. You as the admin can view the mostreads via the members page http://your_blog.antville.org/members
