LQ is a servise that (IMHO) should not be taken for granted. Yes, there are a lot of people with a lot of knowledge, and they love helping out. BUT, i dont think it is fair, to any of the members/moderators/etc. to 'command' them/us to help!
Plus: that statement does not put you into a higher priority. probably members will see your post, and not want to help at all, just because this statement makes peoples help seem unvalued, and not appreciated correctly.
to be honest, i do not feel that i would want to help you because of that either!
but i will! but you need to post some additional info: which desktop environment are you using?
for KDE have a look in the 'Controll Center'
in Gnome look in Applications -> Desktop Prefs. -> Advanced -> Preferred Apps.
hope this helps!
