If its not too much trouble I would like to know what distro you currently use the most.
That way it will enable us to create better how-to tips and tricks according to your distro.
Ill go first. I currently run Fedora Core. So if you find any neat things to do with Fedora Core that I havent already then please post them througout this section of the forum but not in this topic.
Also include the Window manager or Desktop you use as well if you want. I use KDE 3.2 Gnome 2.4
