It's easy to get excited when on social but be careful about how much information you share online. This can range from checking on the privacy options on your profile, so only your friends can see your old photos and updates etc, to not sharing your flat number, phone number etc. Most people are pretty friendly but it doesn't hurt to be a little cautious at times.
