Hello there, hinata_126!
As you may have already figured, tamatalk is a HUGE site! Feel free to explore, and don't be shy about asking others for help!
For a goldmine of help, go to the Extras at the top of the screen, and go to Help. This is a very important forum to keep you on TamaTalk's good side!
Don't be afraid to PM me or TamaTalk guides about problems. I'm sure I can answer most of your TamaTalk or Tamagotchi related questions!
Have fun!
Rachelgotchi
