Remove Content Approval Message from Forms.

Whenever a SharePoint list requires content approval for submitted items, you will find the following message on  your new item forms:

"'Items on this list require content approval. Your submission will not appear in public views until approved by someone with proper rights.'"

I find this message very confusing to my users so I often remove it. 

To remove the message,

1. Go to 'List settings' and then 'Advanced settings'
2. Scroll down to 'Dialogs' 
3. Select 'No' under 'Launch forms in a dialog?' then select 'OK'
4. Go back to your list and select 'Add new item'. Your new item form will open as a page.
5. Go to 'Site Actions ' and select 'Edit Page'
6. Add a CEWP (Content Editor Web Part)
7. Edit the web part's html source code 
8. Enter the following CSS: 

<style>
.ms-informationbar{visibility:hidden;}</style>

    10. Click save 

The message will be removed from the form. 

If you want your forms to open as dialogues again, simply follow steps 1-3. However, in step 3 select 'Yes' instead.
