Yousendit has a 1 GB per month bandwidth limit (only counts how much bandwidth is used when people download your files).
Also, a while back, many of us renamed the ebooks posted on mises:
I have since renamed all of the ebooks to [Mises.org]LastName,Firstname.-.Title.of.Book.pdf and have been sharing them on ED2K ever since.
Also, that was when we (mostly me) bothered Jeffrey Tucker enough to finally stop posting such short and unhelpful title names. It has since gotten much better.
