Is there some way a link to this list could be added somewhere in the *Post* section?
Maybe under *Choose Forum*? Have a statement like, “Please check here to make sure your source is allowed.” and then provide the link to this thread.
That would be very helpful to search before posting a thread only to have it rejected or pulled later.
Yesterday I did all of this work to post a new thread on NATO/Georgia only to have it rejected when I tried to post the thread because the source (a German link) was on the do not use list.
