Hello am I crazy or didn't there used to be a Mark As Unread option for myspace mail and now it's gone?
Nope that has never been a option. You can move emails to different folders but that is it. It would be nice but not possible.
Yes, I don't remember ever seeing mark as unread on myspace either, sorry Anonymous!
Actually I forgot this little tid bit. Messages only show in the senders outbox for 14 days so if you wait the 14 days you can read it and they will have no idea if you read it or not. UNLESS that has changed (it was that way like 6 months ago).
On facebook you can mark a message as unread after reading it - unless that has changed too with all their new changes. I would check by my facebook hasn't changed to the new facebook yet *waiting*.
