Mpreg Central

I noticed that I was at 85% of PM space, so I deleted all of the old messages, both sent and received (they were mostly roleplays that dead-ended) but my percentage remained the same. (and now stands at 87% because I sent a few more PMs since then.) Is this a glitch, or was the site designed to cap the total number of PMs a person could send?

EDIT! I realized I also had to empty my trash can. I'm now down to 6%

Yeah the private inbox system for this particular host is odd. You have to delete everything manually do to lack of storage, but I found this out the hard way. Spoiled by Google!
