Davidville offers you multi-functional services, one of which is Senduit, a temporary file storage area with a maximum duration of one week. If you don't have your own computer or a USB drive and most importantly, you don't want to make your files public on the internet, this is a good choice. It can automatically delete the file within a limited time. There's also one called Tumblr, which is equivalent to Yahoo Space. However, it would be more accurate to say that it's like QQ Space. Inside, you can upload and store videos, subscribe to blogs, and access other functions (such as online cartoon playback, car-related content, and more videos). There are other features too; if you're interested, try it out yourself.
