I've made a widget with all those meters, it's been working on my desktop for over a month, yet when I submit it, the mods say it doesn't work yet people I've emailed it to, say it does.. ahhh the mind boggles.
I've done simple meters (c drive, cpu activity, etc) but when I start getting into RAS, etc, I cease to know what the heck I'm monitoring. Not really a computer whiz over here.
