Sometimes I receive Google Chat messages from people when I'm away, or for whatever reason I'm not able to see them. Right now, I never see these messages, unless I just happen to do a search in Gmail for "chats" or that person's name.
Is there a way to make these chat messages show up as unread messages the next time I'm logged into GMail? Or, alternatively, is there a way to be notified in a different way (SMS etc.?)
