publish_posts without edit_posts

Hi everybody, i have a little problem and i need your help.

What i want to do ?
I want to write some posts for customers, and then let them choose what they want to publish or not without the possibility to edit them. (It is really important that they cannot edit the different posts)

What i tried ?
I tried to use the plugin “user role editor” by creating a role “toto” which have “publish_posts” and “read” caps.

What happenned ?
In the Dashboard the “Posts” menu disappeared and “toto” can’t access the list of the different posts to publish them.

Please tell me there is a solution (even if i have to use something else than user role editor)

Note : Sorry for my english, it’s not my native language…
