I really don't see how the staff simply does not care. All you say is "delete your items then, we have 300,000 members. Too bad"
What the fuck is that? I'm a moderator on a forum with 700,000 members and we have our setting set to.. wait for it..

There is no reason why you couldn't give your members more room for inboxing. Not 300,000 members are going to use their inbox regularly, but the select few that do - do it for a reason. We are here to communicate with your member base here on rollitup.org, and if you limit us to how much we can save in our box, I feel that people just find it easier to find another forum who cares about what their members think.
