gmailverify.js

/*
  Automatically click all "Verify your email" links in the welcome e-mail from
  Nintendo Pokémon Trainer Club's signup e-mails.
  
  Original code by Seb <3
  
  All verified e-mails will be moved to trash unless you set "moveToTrash" to false.
  
  How to use:
   1. Login to Gmail
   2. Go to https://script.google.com/
   3. Enter the code, save, run.
   4. Wait until fully completed, DO NOT LEAVE THE PAGE! (When finished, the text "running..." at the top will disappear.)
   5. Click View > Logs. At the bottom you'll see the total accounts verified.
   6. Enjoy
   
   Note: The script will stop after about 98 emails. This is a limitation of Google Scripts, not the script itself. Simply run again and it will process the remaining emails.
