Yes. Most subscriptions include the Import Wizard. The Import Wizard will walk you through the process of uploading a spreadsheet of your Group members names, telephone numbers, and email addresses.
You can also import your Subgroups from column data within your spreadsheet. You can find the Import Wizard under the Manage Group menu item on the Group Leader Menu.
If your spreadsheet is for a very large Group, simply email your roster file to email@example.com. We will be happy to load the first one into your roster, generally within 24 hours, at no charge. (Additional roster loads are subject to a fee.)
