I got another notification to clear space in my inbox from private messaging someone today. It's easy for me to clear space or archive messages, but it's hard/confusing for some people. As a webmaster/programmer myself I'm curious if there's a reason for the cap. Surely the disk space occupied by private messages is tiny compared to the images people upload here every day, not to mention public posts. Is it just a default setting on the forum, or is there a reason behind it? If it's just a default, could we get it changed?
