I send Pm's but nothing shows up in in my sent inbox? is this a glitch or my account doesn't have enough weight?
Did you check the Save a copy of this message in your Sent Items folder option when writing the message (under it)?
That used to happen to me before the upgrade.. Sometimes it would take a day for the sent items to update & reflect any recent sent PMs. & The forum had other PM bugs then too, but since the upgrade I haven't experienced any of them so far.
