i wish to have the ability to store and retrieve data online utilizing a username along with a password so a userscript that operates on a web page might have personalized information.For instance i wish to write notes for customers inside a forum and wish to retrieve them from the computer that my userscript is installed.

I figured google excel spreadsheets would have the desired effect however i havent had the opportunity to implement it.
