First Of All , Bro If You Want To See What Other Pplz Have Uploaded , This Must Be A Support From The Website Itself , Ya3ni Eza l WebSite Mish 7atet Hal Shaghli Enno Fik Tshoof Sho Ghayrak 3emel Upload , So You Can't. ( For Example , www.tinypic.com Is A Website For Uploading Images , And You Can See What Others Uploaded .)

And For The Second Question , YouSendIt.Com Is Not A Very Good One.
For Me I Use The SendSpace , And Here Is Some Good Websites Man :
www.sendspace.com
www.rapidshare.de
www.hyperupload.com
www.megaupload.com

Enjoy !!
