Article writing site

I am looking for clone of: [login to view URL] website. Design wise will be different but features and the way it operates are great. All that password reminder, resetting etc. all the security like in normal site. Possibilities to add more options from admin panel I would also add website building options to the site. Understandable and easy admin panel. Security options, SEO ready, Also security in a form of communication when somebody writes their e-mail in the IM or communication box it will not be displayed and admin would be notified about it, also possible words such as "email me" "email me at" "dotcom" and many more similar phrases would also alarm admin and send him a message of possible fraud by one of the party to the agreement so he could check it out and take care of the problem. It is an easy site to create with paypal, google checkout and possibly merchant account as a payment getaway.
