Have you heard about Acrobat.com?
I thought is was an online service to create pdf's, but its a lot more. Let me give you a quick preview.
First of all this is a free service offered by Adobe. All you have to do is sign up to take advantage of the free features.

Buzzword - Is an online word processing application much like Google Docs. It looks and behaves like your normal desktop word processor, but it operates inside a web browser. You can share the files so others can collaborate or contribute. Perfect for writing reports, proposals, and anything else you need to access online or work on with others.

Connect Now - This is an online meeting room. Use screen sharing, chat, notes, audio, and video to conduct meetings online.

Create PDF - Provides an online PDF converter so you can easily create PDF documents from your existing files in Microsoft Word, Excel, PowerPoint, and many other applications.  Note there is a limited number of pdf’s that you can produce using this free service. The free version only allows creation of 5 pdf's. For unlimited pdf creation you can subscribe to the Create Adobe PDF Online service.

Share - With your free account you have 2 gigs of online space. So if you need to send a large file you can upload, then select the file and click share. This will generated a link to the file that you can send in an email to the person you want to share the file with.

My Files - Shows the files stored in your area. Whether one’s you created using Buzzword or have uploaded. These files can be easily access from anywhere.

Adobe is offering some great features and the price is right free. For more information visit acrobat.com
