[Plugin: MailPress] Mailpress – How can we select the posts to send?

Hello arena,
I have read the instructions but unfortunately the steps are not very clear. I have a problem with the subcription management page as I have written here too:
http://wordpress.org/support/topic/plugin-mailpress-help-with-the-page-template?replies=1
and no one has replied to me.
What I have to do in order to have the management page in a normal page like I had it in the mailpress default template?

I think that someone has to re-written the instructions to be more specific. I noticed that others have the same problem too.

Thank you.
