Chers Chris. I use su in a command prompt (although the command seems to lose any form of path, and is therefore restricted in what it can run, if you see what I mean).
For convenience, I want to use the taskbar to launch an app, when logged in as me. But that app requires root privs... I had a quick gander at the sudoers file.. er, wtf ist that on about! The manpages look as though they were written by computer for a calculator to read...!
