Can I add 2 more users to this account? There are 2 more office admin who would like to get the jot forms emailed to them as well. Thanks!

You can share your JotForms to other users (sub-user accounts) i.e., you'll be granting some rights to these accounts so that they view the submissions or may edit JotForm. You can create sub-user from Users tab from your account page by inviting them through email.

Please check below the link on how to share your forms with sub-users:
