I didn't see this dealt with elsewhere. Right now I have quite a few sent PM's listed as "unread by recipient" in my profile, mainly from Welcome PM's sent to new members. My PM box is about half full now, and I want to clear out some of the clutter, but I need to know if I delete an unread message on my profile page does it also delete the unread message out of the recipient's box?
I know that on one other board that I frequent there are two separate options, either to recall/delete an unread PM from the recipient's box and to end tracking on a PM without deleting from the recipient's box, but those options don't seem to exist here. I want to get rid of those unread Welcome messages out of my box, but I want them to still be there for the newbies to read when and if they log in.
