I second what wanttoheal said. I know a hug isn't a lot, but sometimes it's all I can think of. It's not to get post count up or anything. There's no perks in it.

I really don't have anything to add as far as changes. No matter what the rules say, people are going to interpret them differently so there's always going to be some bruised feelings and the assumption that some people get preferential treatment.
