Well, we don't delete attachments any more. It was causing way too many problems with continuity in threads. I don't think there is a way to reset it though there might be. I don't think we have come to that bridge yet
I believe the idea was basically to make it unlimited - though some limit had to be put in the box. Like I said I am not exactly sure how high our tech folks set the limit, though it is pretty large. The only way you could probably really get there realistically would be to attach a bunch of videos.
