PPT Sites

Please advice best ppt distribution sites.

Related to his question, with a site such as slideshare, does anyone know if links are preserved within slideshows? In other words, if I wanted to create an interactive presentation in Impress that asks the viewer questions and he clicks links to answer those questions. One slide might link to a different slide, etc.
Can this be done with an embedded slideshare presentation on a website? I might start another thread asking the best way to create this type of presentation in case it’s not slideshare.
