Private messages - can they show as a conversation?

[2kidsintow]

I'm in contact with a few (fab) people as a result of mnet and we private message each other. It's quite frustrating that I can only view the last message that I sent them rather than our whole conversation. I'm sure i'm probably writing things again to them that I've already said, for example, but I can't see all our messages to see.

It would be great if, like fb, if you were messaging someone, you could read the whole conversation.

Thanks
