Hello all,

Box.net is a great place to store/share files for free
Mozy.com allows for free back ups of up to 2 GB, you choose which files to back up and the times that it backs up (personally I have mine backed up every 3 hours, and did choose to pay due to my computer having crashed 2 times in the last 2 months). You can actually obtain more free space by referring Mozy to your friends and family and having them sign up thru you - still no fees that way and it increases your free storage space.
PDF Hammer (from Tess in a different thread, thanks so much Tess)- this is a great site for editing your pdf files in, you can combine several, remove pages from another, resort and then save your new pdf file.
CutePDF - this is a free download that allows you to create a pdf file from any application, download and this is added as a printer. When you print to the CutePDF it creates a pdf file - you just name and save.
GoogleDocs is great as it allows for sharing of files, spreadsheets and calendars.

Thanks to all of you who have shared these before. I love using them regularly and happy to share my favorites.

Okay, one more,
TeamViewer.com - this is a site that allows for working on a client's workstation for free - like gotomypc.com but for free. You can share files and make changes as you need to all from your computer.
