Well, if a reputed site hires me as a signature manager

, or while sending PMs to a member here, or while making a post, is the use of emoticons or smileys considered appropriate?
Wanted to know how you guys think. Thanks

It depends on the circumstances, the subject being discussed and what you're linking the emoticon to. Not everyone likes to see them in serious discussions, but if you don't overuse them you should be okay.
