The PM box holds only 40 messages. I've found that this can get really restrictive, especially when I can go through that number in a day or two. Is there any way to expand the inbox?
Very shortly (some time today) I'm going to put in some hard limits on the number of PMs that people are allowed to keep on the system. Four of you have several thousand. A number have more than 100. I'm likely to set the limit at 40 or so. This isn't an email system!
