Importing users into Asset Bank
Users can be imported via a tab-delimited file. This functionality can be accessed via the Import users link at the bottom of the Users page in the Admin section. The User Import page contains instructions on how to use this functionality.
If you use the Email New User checkbox (introduced in Version 3.1538.9), then they will receive an email letting them know they have been added and asking them to generate a password prior to logging in.
The email template can be found here:
