Drop.io is a good service if you want to upload files, share and collaborate privately. Search engines do not crawl drop.io. and you can set your drop to be password protected. It is a very easy and simple service to use. Just create a drop and you can copy the url and send it to your friends. There is no need to register to use this service. Drop.io was launched in 2007 and won several awards. The free drop only gives you 100 MB but that is still sufficient for most users. Otherwise, you can upgrade to a larger amount. Instant messaging chat is also available within your drop. Each drop is also very customizable. This is really a nice and easy service to use. Click on the link below to visit their website.
