ive checked and cant find anything about any option for users to delete their chat box history. will there be such an option or is there a component for this ect? this seems such an obvious option to implement im surprised its not available even in premium installation.
If you see changelog for v5.x (a future version have option to delete messages) : https://github.com/opensource-socialnetwork/opensource-socialnetwork/blob/v5.x/CHANGES.txt
the function you want is OssnMessages->deleteUser($guid). that function deletes all messages to/from that user. I think you should build something like this, I agree that it would be useful to have a way to clear chat history.
