What are you psychic, Julie? Attachments to PM’s are one of the several new features for the 'esteemed member' user group! LOL. We have been working on that one for about a month now! We just have not been able to get it stable with this version of the forum software.
As it stands, PM CC's and BCC's are limited to two total per message. Same number as it has always been. This will not change across the board for all users since increasing the number will actually slow down the server.
Cheers!
