I also access PC via mobile, so I don't get 'thanks' or 'hugs' button responses, in answer to your question. I make a point of asking for what I need, cos people can't smell it...

Wether I need support,advice, to hear that I'm not alone, if someone's been there before, encouragement. Or sometimes I just need to vent, and these posts I don't expect any replies on, but I've made some great friends here,so even those threads have replies.
I think it's important to communicate our specific needs.
