Why hello, Cat person! If you want, you can register, but it requires a username, password, and an email. Now, if you don't want to, that's perfectly fine! But that may be the only way to protect your username. Its optional. :)
If you have any problems in life, such as bullying, the KidzTalk kids can always help. And if you have any KidzTalk problems such as forgetting password, (only if u register) just make a post under, "Ask Kidzsearch"
I hope you enjoy KidzTalk as much as I do!
