How do I make a custom page with custompress

I could not choose custompress from the plugin menu. Maybe its because I have installed classifieds, and it was with that plugin. Therefore I have just choosen classifieds, but it is custompress I need help with. But now to my question.

Is it possible to make a page like these two:
http://www.businessbee.com/resources/news/
http://blog.chegg.com/category/student-voice/

I would like a page similar to that on chegg where people can have a wall like that and post into it. Do you know how I make it. It looks like a blog page, but a blog that is public and all can submit their posts. Can I make that with custompress?
The users should be able to submit news with a picture attached and other users should be able to comment on the post.

I think that custompress is a little complicated, I hope some of you will help make it.
