I have wanted to get to know people in Hogwarts, so when I went to their bio, I discovered that A. they didn't put anything in it B. They put to much in it And C. They barely wrote anything to tell me about themselves. So, I felt like this was a good Step to put in here. Here are the things that should be in your Bio:

1. Your name

2. Put the things you like in it

3. Tell about how you found out you were a witch/wizard

4. Make sure its No longer than one (or 1 1/2) paragraphs

5. Include some humour!

That is basically a good way to make a good Bio! Here's and example for a good Bio too if you need it:

 My name is (your name) and heres a little bit about me. I like the movie (favourite movie), and the movie (movie). I love making (cookies, friends, potions, etc.). I found out that I was witch when I was playing with a stick (not a stick apparently) and nearly killed my dad! I was shocked to find out that I was a witch. Please add me!

(that was just an example) I hope you enjoyed that, and have made an incredible Bio! Your close to finishing! Keep reading!
