How do you give lurve?

Apparently I’m annoying everyone by being new and having no idea how to use this discussion board. I’ve been looking around trying to figure out what this mythical lurve is and how to give it and how much of it to give and when but I can’t find anything. Please don’t be mean, I’m trying to learn how to use this. I already searched the collective because I imagine that others have asked this question but I am obviously doing it wrong because I can’t find anything. Didn’t realize that there was so much to learn just to ask a few harmless questions :)
