Is there any way where i can have any user in a group being able to edit ALL the articles in a database regardless of who is the creator?...

With WIKI STYLE=OFF one can edit only their own pages.

If i enable wiki then ALL can edit all articles..

Use Case:

I created a simple helpdesk where i need ALL the members of AGENTS group to be able to edit ANY post, but USERS group must be able to edit ONLY their OWN topics.

ALL should be able to comment.

How i do it?

 

Include permission of your group AGENTS database for this page

I opened a ticket about it also, and the response was that the only solution for this is to make the agents belong to moderators group also.
