What does the stamp drop down menu in the render panel do? I am working on a project right now, and during the render process I noticed a little check box that says stamp.
When I selected the drop down menu it had a bunch of selections the refer to text and font, and things like that. 

My scene has text in it, and I was wondering what this section does, and how it is applicable to text scenes.
The Stamp section in the Render panel goal is used to draw some information on the render output. This can be useful for a work in progress production.

See the blender wiki.

For example you can select Frame to print the current frame number on the final output.

The Font size, Text color and Background settings allow you to control how this information is displayed.

You can additionally print a custom note by checking the Note setting and writing whatever you want.
