Why do you not have a function to review alert history?

When logged into Seeking Alpha, there is a bell icon that shows you current alerts.  Sometimes, without warning, all my alerts disappear.   What other sites do is give you a menu option to "review all alerts" and that is a permanent record of all of the alerts you have ever received.   It cannot be shortened or wiped out.   Why don't you have this feature?  It would allow us to recover when the alerts feature does not work perfectly.
