Issue with my PMs
 

My sent box shows 0. I did not delete any sent PMs. I have one in my inbox from the person who replied to a PM I sent them, that one being the first PM I have sent on this forum. I believe I sent them another reply, but sometimes I type things up and with 30 windows open jump around and don't come back. I don't want to send the same message twice but it doesn't seem that I have any way to tell if I did.

You need to have the option in the settings to save sent items. If this isn't set then you'll not see anything in that folder.

For the situation you describe I think sending a second response is probably best.
