Good question. First, click on a tool in the tools engine. This will bring up the following interface:

As you can see, there are four tabs along the top of the toolbox:
Upload/Download – This is where you can download a utility or directly upload your files to be processed by our server, depending on the type of tool.
Info – This is where you can find more detailed information about the tool’s function, use and revision history.
Feedback – This is where you can read other users’ comments and suggestions about the tool. (There is a section for rating each tool near the bottom of each page.)
Author – This is the where you can find information about the tool’s developer.
And that’s that! Feel free to try them out. The system is pretty intuitive; we’re confident that you’ll figure it out with relative ease.
