I can do it, I'm new to this site but I have more that 10 years of web development, so I am focused on a work done, happy client and a nice review. ...veo la bandera de España en su usuario, si lo prefiere podemos comunicarnos en Español.
If I understand you want in this project the following:
1. User registration (with email activation link).
2. User login.
3. Form page in front-end to create new proposal for logged in users. Proposal have following attributes:
* Title
* Content
* Published (default: False)
* User
* Date
4. A moderator are staff members and has access to the admin backend.
5. In admin backend moderators can publish proposals.
6. List Page to with all published proposals (no login required).
7. Detail Page to view a published proposals (no login required), if a moderator is logged-in a button to publish it is appear.
8. UI Theme with twitter bootstrap.
If you want I can add a function to send email to moderatos when a proposal is created with a link to the proposal detail page (point 7). Email to the user with yes/not approve, Also I can add attributes to track date and moderator whou approve the proposal.
I can start ASAP.
I have big experience with python/django, javascript/jquery and twitter bootstrap. I use this skils in my previous completed work in this site.
Yours,
Julio Cesar
