Recently, I found that Badongo is not like before. It has the CAPTCHA feature like other 1-click hosting website. So, I try to search for other alternatives.
And I found that, Windows Live SkyDrive offer 5G online file storage. Besides that, it can store personal files, share the files with friends, and also share the files publicly. Therefore, I think this is an alternative to share the file publicly. However, we need to sign up an account before using the service.
