If 1MB attachments were regularly sent on this list, I might agree with
you, but they're not. There is no epidemic of huge attachments being
sent to the list.

I have kept all messages sent to this list since January 21 of this year.
I just ran my attachment manager plugin on those messages. There were
142 attachments for a total of 909,498 bytes, *including* HTML
attachments. The largest was 111,573 bytes. The second largest was
34,856. If you remove the HTML, there were only 51 attachments totalling
571,076 bytes.

So, of the binary attachments, the average file size is 11,198 bytes, or
just under 11 KB. If you take the single "large" attachment out of the
picture, the average size of binary files drops to about 9 KB.

When you come to think of it, the binary attachments consume about 7.5KB
worth of bandwidth per user per day. The HTML attachments average 4.5 KB
per user per day.

888KB is nothing compared to the amount of bandwidth the messages on
this list take up.

On any other list, I would agree. If this were Usenet, I'd agree.
However, Full Disclosure, by its very nature, needs to be unmoderated
and unfiltered. That's what makes this list unique.
