To use the Ministries and Small Group Modules, just click on the Ministries link on the navigation bar inside Connect Manage. Add a ministry by typing its name in the field and clicking the plus sign. You can add as many people as you like on the right to designate that they are in the ministry. When you click the edit (pencil) icon, you are able to designate them as leaders or change the date they joined, in case it is not the day you add them to the ministry. You can remove ministries or people from ministries easily by clicking the trash can icon.
The Small Groups module works the same way as the Ministries module, but is specifically for small group Bible studies. You can rename the small groups program on the Church Settings page. Here you can also enable or disable the Ministries and Small Groups modules. Please see related article for more info.
