Hi Does anyone know of a article management system where I can add users and they post up articles but I have to check them before they can. It must be simple to use, thanks for any help
A self-hosted Wordpress installation will do the trick. I believe that you should set the new accounts to 'contributors' -- they can edit their own work, but they can't actually publish it. You'll also want a couple of plugins: Manage Your Posts Only Draft Notification The 'manage' plugin makes it so that contributors can only see their posts -- not everybody's (even though they can only edit their own). The 'notification' plugin will send the admin an email when a draft is saved. If I remember right, it's annoying because it does send when drafts are saved, not when an article is marked 'pending publishing' or whatever it is. However, this is the only way that I know of to get notifications when writers contribute work.
As mentioned already, WordPress is ideal for this. I recently created a site that is being updated by a team in an office that really don't know anything about computers but they have been able to add posts easily and without much instruction at all. Then their posts go through a moderation from the office user with the power to approve them. So far that's the best thing that I've found to handle this situation. You can have as many different user accounts as you want so if you want to monitor who a post is coming from then just give each of your contributors separate login details. It's really easy within the WordPress control panel for you to set up user accounts for them. Hope that helps and good luck with it, Bex
