What does the smiley face mean?
Is it just another helpful option?
It means you are madder than you have ever been in your entire life! j/k It means just what it looks like,......you are smiling. :-)
It means its fun, or funny i think.
I am guessing smiling. But that is just a guess.
:) smiling. Being polite, or your happy.
It's an emoticon, it means simply : Happy. Or any related words you can find.
A thumbs down with a smile.
It means "Your answer wasn't very helpful but it was sure was funny." Or it could be helpful and funny. I double-vote where applicable.
