Resending a welcome email to new users
You can re-send a welome email to new users within settings -> users, by clicking the 'email' button to the right of the user.
Users who don't have a 'send welcome' email button next to their name have already created a password and logged in - thus you can't resend them the welcome email! If they have forgotten their password, they will need to go to the ExpensePlus login page then click the 'forgotten password' link and follow the instructions to reset it - click here for the instructions to do this.
