When I ask a question on Ask Ubuntu, I usually end it with some kind of request for knowledge, like "does anybody know the actual *meaning* of this message?". A lot of newer people end the question with "pls help!!!!!", which I'm pretty sure automatically marks them as a noob. Still others end it abruptly, but with the complicated nature of Linux and especially Ubuntu issues, this can make it unclear what they're asking.

What is the ***best*** way to close a question, making it clear exactly what you want, but without turning people away or being unclear or rude?
Moderators and developers, what do you like to see most?
