When introducing yourself:
- It's adviced to not tell anyone where you live.
- You can give out your full name and share your FaceBook profile or whatever but remember you're online; your information can be shared all around the world and some people might use it for bad things.
- You are allowed to post a photo of yourself if you want to, but it's not needed; because some people like their privacy.
- When someone doesn't post their picture or last name, don't ask or beg for it; they don't want to put it up for a reason.
That's all I guess. Have fun~ <3
