File Storage.

MediaFire (2009), is the simplest file hosting service to share files and images with others.
Here's what you get:

Direct/Hot link to files
Up to 10GB per file
Redundant backups
No Ads
Rollover bandwidth
SSL encryption
Advanced statistics
Priority support

Unlimited storage
Up to 100MB per file
Unlimited uploads
Unlimited downloads
Unlimited bandwidth
Image galleries
No sign up required

After the easy file-upload process, you can access your data from any computer and post links to the files for sharing with coworkers. For example I would utilize MediaFire by using it as a collaboration tool. Effective communication would be made simpler for exchanging and storing resources with other teachers. I especially liked the upload progress page, which gives you a great view of your upload progress, speed, and estimated time to complete the upload. Here is the file on my unit on Biodiversity for a Year 6/7 class. http://www.blogger.com/
