When you are working on a collaborative project, you may want other people to send files and documents to you.

Now instead of using email attachments and clogging up the mailbox, what you can do is use DropItToMe.

The service create a special upload link (URL) that you share with all the people associated with the project. When they upload files using this special link, they will magically appear inside your Dropbox folder.

The upload link is protected by a password. Also, while most email program only allow users to exchange email attachments between 20-30 MB is size, DropItToMe allows file uploads as large as 75 MB.
