The creator creates a group based on the instructions described before in previous sections and adds how many members s/he likes over her/his contacts. All members are able to send messages and see others’ messages; also if one of them wants to add a new member, s/he should ask the admin/creator to do so. Additionally, the rules for members in this group are specified by the admin/creator.
For public groups the creator should identify a username for the group after creating based on the instructions. So, everyone- who has an iGap account- can join by searching the group’s username. In public groups, there is no need to be added by admin/creator. If you as a member want to add a new member, just send the group username to others, then they can join by touching or clicking that. In this sort of group, all members can post and everyone’s posts and messages are observable to others.
