I just noticed this message in the PM corner of the screen. Went to check, and apparently the size of the PM mailbox has (recently?) been lowered to 500.

I'll have to go through and winnow out, since I'm about 100 over the new limit. How long do I have to do this?

What happens (and when) if I don't reduce the number? I infer that I won't be able to send or receive until I do free up space, but will there be a mass deletion of messages over the limit? If so, how would that be decided (oldest ones deleted, or some other rule)?

Sorrry if this information is posted somewhere else, but a "search" didn't turn up anything.
