You should now be able to access http://docs.google.com and create a document to be shared either with your staff or with your students.
Take some time and experiment with some of the different tools. Try to create a document, a form, and either a spreadsheet or a presentation (each of which you may actually use).
You do not need to complete each of these, but start each one with at least a little detail and invite your classmates here, and those other staff who might benefit or whose input you might want, to either view or help edit your files. Be sure to invite me to be your collaborator too!
The quickest way to learn to use these tools is to simply use them. Experiment. See what happens when you try certain commands and options. I will answer as many questions as I can, and help each of you as you need help.
Have fun. I always do. :)
