This is an example of how you could do the 
gig sheet on notepad as a text document and 
then each time you wanted to change it you
would just make a new one on your computer
and upload the file to the site and saving
it over the old one (very easy).

date   -    location   -   whatever else!
date   -    location   -   whatever else!
date   -    location   -   whatever else!
date   -    location   -   whatever else!
date   -    location   -   whatever else!
date   -    location   -   whatever else!
date   -    location   -   whatever else!
date   -    location   -   whatever else!

Only thing with this type of gig sheet is
you cant put a link on it for directions.
