The size of the PM box needs to be at least doubled. Now that I'm actually doing some deals on this site, it would help to have a bigger box to store everything, especially if I need to go back and reference an old message.
100 is more than enough.
Just make sure you guys delete sent messages. There's a check box when
sending a message that you need to uncheck, that way your message will
only be 'tracked' and not save copy to your box.
Sometimes it's nice to have a record of how a transaction progresses, just in case something goes wrong. Anyway, I'm not all that intent on increasing the PM box size, I'm just saying that a little more room would be nice.
