At the time of writing, there’s no Admin UI for granting badges in bulk in Discourse. So we have to do it the Old Navy Way, on the Rails console…

```
emails = [array containing all the email addresses of attendees]

# initialize blank array for User objects
userlist = [] 

# pulls only Users where the email matches the one they used for
# Summer Sschool registration without causing errors
emails.each { |e| userlist << User.try(:where, email: e) }
# the use of try avoids errors when no match is found

userlist.reject!(:&empty)
# get rid of any non-matches which are an empty entry in the array
userlist.flatten! # flatten the array by one level

# BadgeGranter requires the Badge object and the User object
# to be passed in as parameters
# In our case we were assigning the Badge with the id number 108
userlist.each {|u| BadgeGranter.grant ( Badge.find(108), u ) }
```

Done!
