What is a good website similar to Google Docs where I can post PDFs and Word docs?

I also plan on sharing this account with quite a few people, so if there's a website that allows sharing of files within a group, that would be useful too.|||Skydrive - http://skydrive.com - is good. 25Gb of free space. Dropbox - http://dropbox.com - 2Gb of free space is also good.|||Definitely try http://db.tt/RTxDi4Y (dropbox) , its a wonderful filesharing service. You don't even have to copy paste file, just open the file and work on it, when you save, it will be available to everybody with who you have shared the folder. Btw if you pass this link http://db.tt/RTxDi4Y to your friends who will use dropbox, they will additionally get 250MB of disk space , 2gb is already free.|||You can try Zoho who have a product suite similar to Google Docs and also in some ways more comprehensive.
