Few more questions

Hey Guys,

 
Thanks for answering my previous inquiry so promptly. I have a few more
questions:

 
Is it possible to disable and acknowledge alerts via email, how?
Can I configure a maximum time limit a alert can be acknowledged for?

Can I restrict what hosts can be disabled on the enable/disable page?

Can the SMS alert format be reconfigured to display more or less
information?

 
Thanks!

 
Regards,

Greg
