it is possible

I am looking for a module / plugin with which I have the possibility to allow other users to posts you write. For this purpose, you should can also select categories.

Furthermore, it would be great if a user a private CP where would halt is how many articles he has written and such.

Something like guest authors indicated.

Last but not least let others can comment on articles and review .

I am not familiar with programming from unfortunately. I hope that something with a plugin combination is possible.
