Hi Brett,
I reinstalled the updated files, and after that I also installed the PM Email hack you did, (I admit I'm being impressed by your hacks) but when I got in my board, I noticed that all the message I've had in my Inbox, (which are already read) were now all bold. I opened one and got back to the list, it was still bold.
It was easier for board members to realize which PM was unread and which was read, because of its "bold" or "not bold" subject. Any way to fix it?
P.S. I tested the PM Email hack also, but it didn't send the email, nor even give an error that it couldn't send, though I am able to receive email message when I get a PM from a member.
