Build a bug tracker in 5 mins
I like this. From mattf’s shinily resurfaced blog .
- Go to google docs, click new spread sheet
 - Click form, create your form with title, description, severity (1 minor .. 5 epic fail), who’s responsible in a dropdown and reported by.
 - Save your form
 - Add conditional colouring in spreadsheet on severity
 - Add a completed/status column
 - Embed form onto a page/email form to bug hunters
 
Love the simplicity of this.
The only thing I’d add is that you should go into the resulting spreadsheet, go to Share | Set Notification rules and have it email you whenever anyone submits a form right away.
