Hi,
I just wanted to share my idea of backing up my favorite sounds and making them available online from other computers.
I use Dropbox to do this and it is very practical. Free 2GB online storage and syncing with a regular folder on the computer. Also you can have access with your cell phone.
You can register at www.dropbox.com or use my referral if you like with this link: http://db.tt/VbXEGy3 (if you use this link, you will get an extra 250MB of storage)
