How to show a message in the edit field of Activity?

Hi Kyle,
It is related to www.joomlapolis.com/forum/153-professional-member-support/243269-keeping-tabs-of-what-the-admins-do
I would like to show a message in the edit field of CB Activity, ie when a user edits his own activity or his own comments ("Please note that all edits/deletions are tracked within the system")

Do I have to do that with 'activity_onDisplayStreamActivityEdit'? I have never edited a display beforehand so some help would be great (I will do this kind of AA a few more times...)

Thanks very much!

activity_onDisplayStreamActivityEdit will directly output results of an auto action at the bottom of the edit panel for an activity entry. So a Code action with Output set to "return" should work to output something. Your code action can just be left as HTML mode.

Worked perfectly.
Just realised another thing. A condition was missing. Just added myself
Value
[user_id]
Not Equal to
[var1_user_id]
