I've sent some messages (pm's) to my clients.. But I can't track those Every time I see only "You have 177 confirmed and 2 unconfirmed private message receipts." (without quotes). I've observed this from the time the new template was implemented here.. I though that coders might be working on it, but it has been rectified yet Please rectify the bug..
Are you sure you are clicking the "Request a read receipt for this message" option (at the bottom when you send a PM)?
oh oh !! I wasn't knowing about that But earlier it was by default..So I thought it to be bug.. sorry Now, how to change the default settings , so that I needn't click on "Request a read receipt for this message" every time I pm someone ?
