How I can delete a recieved Personal Message ???
You can’t – that would delete it for both users.
So if Sally PM’ed you, and you deleted that PM, it would disappear for her as well.
Instead of delete, how about soft delete? It still exists, a check would see if the user soft deleted it then no longer show it to them. On the opposite side(s) a note would exist saying the other user left the conversation.
This may help with harassment situations. A user that flags a PM they think is against the community’s etiquette then can have the PM removed (soft deleted). That shows their willingness to flag and drop; not stir a troll’s hornet nest.
This shows in full that a user no longer wishes to participate in a discussion. Same as mute, but also removing it from the PM list.
I suppose people are asking to “hide” PMs, so they no longer show up in the list?
