Jira email notifications

[sridhar inuog]

Hi,
       Is there a way to get notifications whenever a jira issue is
updated?  The only place I can see this can be enabled is

 profile -> Preferences -> My Changes (Notify me)

Even though the description seems a little bit misleading I don't see any
other place to make any changes.

-------
Whether to email notifications of any changes you make.

Any other places I need to change to get notifications?

Thanks,
Sridhar
