How To Delete A Conversation (Private Message)Security/permissions have changed a lot. Looks like once you post something, it is permanent. This applies to posts on threads as messages/conversations as well. Nice software upgrade by taking two steps back. Yea baby!
There is no limit to the number of conversations. You can keep them indefinitely. If you choose to have one no longer display to you within your conversations, you can simply click near the upper right of the message to leave the conversation
Once you leave a conversation, it cannot be restored unless you are invited back to it.
For leaving conversations in bulk (full page) you can do the following.
Open your conversation box. Add a checkmark next to the conversation title.
That will open a drop menu near the bottom. Add a checkmark to "Select All".
Although you can add checkmarks next to each conversation, once you select any, a drop menu near the bottom will appear. If you want to leave conversation in bulk (such as a full page) Add a checkmark to "Select All".
Click the drop-down menu next to “Choose action” select “Leave conversations”. Click GO.
