Recomend a plugin to combine with WordPress Guest Post

Im using WordPress Guest Post Plugin to let anyone add an article to my page. What id like to do is add registration, so that people can register, have their own page on my blog which lists all of their articles. I don’t need users to be able to connect (send msg’s, add as friends etc.) with each other, all i need is that they can link to their page which has their articles.

Any suggestions on plugins to use?
