It's not really merging. The scenario is as follows:
My older brother wants to quit CS and our younger sister wants to start playing, she just turned 14 and my mom didn't want her using a website where she can talk to other users before that. He wants to give her most of his pets. Does he need to pm an admin about it once our sister makes an account?
We didn't realize that we could just change his username. (She didn't like his current username) So it's all good.
