As a Page Contributor or Page Manager, you may or may not be trained OPSEC or Public Affairs review of content.
The following might help you avoid content that would cause your page to be rejected.
What should go on your page?
At a minimum, a description of your mission and contact information. Think what your audience would find useful -- My motto is "Think Services First." How does your program serve its audience? If you were searching Google for that, what would you look for? What would you - in the shoes of your visitor - expect to find on this page?
I don't have time to set forth an IEW-specific policy of dos and don'ts. In general, keep things you don't want to share with the world on SharePoint and things that do not need protection on IEW.
To get a feel for what goes and what doesn't, scan AR 360-1 chapter 5, especially sections 1-3 and 14-49 (scan headlines; most of these aren't applicable to you)
Here's an excerpt from another section of the reg. Check this out as well.
AR 360-1, 13–14. Official Web site publishing guidance
a. All information residing on a publicly accessible Web site is public information. Information contained on Web sites is subject to the policies and clearance procedures listed in this regulation for releasing information to the public.
d. Official Web sites or Web logs (blogs) should not have any information that is considered nonreleasable.
Nonreleasable information is any official information that is generally not available to the public and that would not be released under the FOIA. Examples of information prohibited from public release include, but are not limited to,—
(1) Classified information.
(2) Casualty information before verification that the next of kin has been formally notified by the military Service concerned.
(3) Information protected by the Privacy Act (for example, age, date of birth, home address, marital status, and race).
(4) Information regarding incidents under ongoing investigation.
(5) Information or imagery of U.S. Coalition Forces without an official release signed by the individuals in advance or of enemy personnel killed, wounded in action, or hospitalized.
(6) Information that misrepresents the Army or statements in conflict with good order, morale, discipline, and mission accomplishment.
(7) Photographs containing sensitive images, especially those showing the results of improvised explosive devices strikes, battle scenes, casualties, and destroyed or damaged equipment.
e. The PA officials responsible for posting unclassified information to official Web sites, regardless of domain, must complete the Web site training course offered through https://iatraining.us.army.mil. This training also applies to Soldiers, DA civilians, and supporting contractors who review, post, and maintain Army content on non-Army.mil Web
