When you added users, if you chose to withhold the invites or you have a user who didn't receive theirs, then you can resend.
You can identify the users who've not yet logged into Timetastic and created themselves a password by the sad face against their name in the USERS page.
Send an invite to a user
Simply click the 'Send invite' link and the invite email will be sent out immediately.
Sending invite to multiple users
If you'd like to send the invite to more than one user, tick the boxes next to the relevant employees or the top box to select everyone.
Click 'Options' then select 'Send invite email'.
The invites are sent immediately.
