In light of recent events here at Celestial Heavens, we would like to remind you all to change your passwords, both for this site and others you may frequent. I'm sure you're aware of the general advice when it comes to passwords: use many letters, numbers and special signs, making sure that the password is not easily guessed by people or bots. A good tip, in fact, is to have extremely difficult passwords, and different ones for every site you visit. To remember them, write them down in a small book or leaflet and put that on your shelf. The thing is, these days it is much more likely that your passwords will be stolen through digital means such as hacking; burglars are unlikely to rummage through your house looking for that little book with passwords. If they do break in, they're going for phones, tablets, jewelry and such things.
