I had the exact same problem, and I’m no beginner at computers & the web. I eventually found out how to edit/create member pages.
What you have to do is (ensure you’re logged in, obviously) then go to Member Pages (under the heading Panty Pleasures on the left hand menu)
Under the search facility, type in your user name, or name of your site, anything which might bring up a result. Or you can scroll through the member sites until you find your one. Even if you havn’t created a site yet, you should still be in the list.
Click on your site and you should get the create/edit/settings etc menu along the top of the page allowing you full control of your member page.
I hope this helped someone – it took me ages to work out and I don’t know of a shorter method I;m afraid (unless you bookmark the page 😉 )
