Community Server allows you to display the forum post edit notes to all users, even those who are not forum moderators. This means that any edit notes for any edited post will be displayed.
If you edit Themes\default\Forums\thread-flatview.ascx and Themes\default\Forums\thread-threadedview.ascx, change the following code
<CSForum:ForumPostData Property=”EditNotes” runat=”server”>
<DisplayConditions><CSForum:ForumConfigurationPropertyValueComparison runat=”server” ComparisonProperty=”DisplayEditNotesInPost”
Operator=”IsSetOrTrue” /></DisplayConditions>
<LeaderTemplate><br /><br /></LeaderTemplate>
</CSForum:ForumPostData>
with this code
<CSControl:PostData Property="EditNotes" runat="server" />
When you make this change, however, you forfeit control of toggling the display of edit notes in the Control Panel and force them to be displayed when they are provided.
