It would appear you don't know how to use vi. It might be easier to try with, e.g., nano instead until you have the time to learn. – XTL Jan 8 '13 at 8:49
10 second vi primer... First, use vim. Second, type i before trying to insert anything. Third, type ESC to get back to control mode. Fourth, type :x to save and exit. Fifth, Google it. – Alex Chamberlain Jan 8 '13 at 9:17

Have you solved this issue yet? If so, could you please create a self-answer and mark it as such. We are trying to get the Q:A ratio up and that would help us a ton. Thanks! – RPi Awesomeness Mar 3 '14 at 17:59
you don't need editor to add just 1 line to a file. Use echo. sudo echo "bcm2708_wdog" >> /etc/modules should work. – gurcanozturk Sep 16 '14 at 18:53

You seem to have issues with vi or vim. Either you learn how to use vi/vim, or you use a less advanced and much simpler editor like nano.

If you want to edit /etc/modules then you'll have to do it as a superuser, ie

sudo nano /etc/modules
