@Frankief and BluesBrother:
Having or not having karma points is immaterial. Everyone has a home who wishes to be here. Everyone is wanted. The number under your name doesn't define "accepted" or "unloved/unwanted". Make friends with whomever you find you wish to be friends with and forget ranks and points.
Be yourself, don't worry about numbers. Relax and enjoy yourselves. No one here is going to like or dislike nor befriend you based on your rank, member number nor karma points. Anyone who does isn't worth having as a friend.
You'll find people who know eachother since they've been here longer....but that doesn't mean much since as you're here longer, that feeling will fade. You'll learn the slang and all sorts of stuff.
It's like being the new kid in school...if you've ever moved, you know what I'm talking about. The other kids will get to know you and all will be well.
That feeling is universal...no one was born here. Don't blame karma for your feelings of 'newness'. "The fault dear Brutus is not in the stars but in ourselves."
Try not to be too sensitive.
Welcome and have fun. Don't be afraid to ask questions nor say hello.
