Help How do I control my alerts? (e.g. Power Saving, Touchdown app etc)

[ship69]

Hi

I am getting far too many alerts from far too many things!

e.g. the every time the "Custom Power Saving mode" kicks in, it appear on the home screen...

e.g. every time I get a few emails it buzzes and makes a noise
(I *think* that I'm using Touchdown for emails...

But how do I control the frequency and/or disable the alerts completely?
With thanks
J
