Clarification on SlideShare's Terms of Use

I have read about SlideShare from a book, visited the site and I'm interested in signing up as a member.

I've read the Terms of Use and there's something that I'm not too sure about and wish to clarify:

1. May I ask if there's a limit to the number of links a particular slide or the whole slideshow in a slideshare slide can have?

2. Is it possible that, from a slideshare slide, we have links that whenever people clicks on, will direct them to a particular product site where they can purchase a particular product (where if he/she purchases the product, we'll be paid commissions)?

Appreciate your clarification on this. Thanks!
