Running Icebook w/closed lid

[PaulKurtz III]

I have a couple year old Icebook and just upgraded to Jaguar from OS9 and
installed a 5400rpm 40GB drive.  Now that I have OS X, I decided to make the
most of it and just downloaded NoSleep 3.0, a program that keeps it from
sleeping when closed. I have 2 questions if anyone knows anything about this
program.

First, once installed, how is it removed?  Can I just drag it from the menu
bar?

Second, does anyone have first hand knowledge of the heat issues, or lack
thereof with the lid closed?

Thanks,

Paul
