Brian Dropped a zero. I played with some numbers about 6 months ago and came
up with a break-even point of about 120-200 people (what I was looking at was
when a mailing list became large enough to be cheaper to the net as a
moderated group).


Actually, reposts are quite simple. The algorithm I've used for years is:

    if (I need something)
    {
	ask the net to tell me if they have it but not to send it immediately;
	if (I get multiple replies) 
	{
	    ask the first or closest for a copy
	    thank the rest
	} else /* I get one reply */ {
	    ask for a copy
	}
	if (I get a few requests for it [<5-10])
	{
	    mail out copies
	} else {
	    repost
	}

I've never been inundated by copies that way, and the control of the
posting remains in a single source -- the original requestor. You don't
end up with 99 people posting a version of shar to the net, and everyone
is happy.

It's not looking, it's heat seeking.
