Open up a conversation and then hit the berry button. Find Chat options and set it to forever. I think you have to do this with each group/conversation.

You're right, this option doesn't seem to show up on individual chats, only with groups. Sorry I thought it would be common. I guess the work around is to set up a group with just you and the other person?
