Limit CMS Article Editing

[Budget101]

I want certain usergroups to be able to add CMS articles, but once they're checked, approved & published by the admin, I don't want them to be able to edit the article any longer.

Is there an "if conditional" I can wrap around the Pencil edit button or any other way of doing this?

Thanks for any and all ideas!

Another way to do it is to have them post the article in a thread and then you can Promote to Article. Then they don't need any permissions in the CMS. Or, have one section in the CMS where they submit their articles and they have privileges, but then when you approve it, you move it to another section where they do not have privileges.
