A static group is simply a saved search, whereby the results of the search are saved to a group and will never be automatically updated.
Click Advanced Search.
To create a static group select the 'Save To Group' option in the right corner of a search results screen. Then a pop up box will appear for you to enter the name of your new group. E.g. TY. Click Save.
Your new group will now appear under the Groups tab.
Here you can send a SMS for this group only by clicking the mobile icon. See SMS & Email section for more information on doing this. You can also do a Bulk Attendance for the specific group by clicking the Attendance icon. See the Attendance section for more information on how to do this. Also you can delete a group at any time by selecting the trash can icon.
