This helps users to create groups (ekips), which they can directly assign a payment to all the people in it or create a turn-based activity inside it, or plans.

Idea: A group can be a user-type which the first friend is always the admin, it can't have less than 1 friend. like any user it has it's own private invite code, which can be renewed when requested to enhance privacy. like users it has a public field which defines its visibility in search.

There would be several actions for GroupService:

• Create and Get operations.
• JoinToGroup: adds user to friend list of the group and vice versa
• LeaveAGroup: removes user from friend list of the group and vice versa
• RemoveMember: managed by admin of the group.

This helps users to precisely define the day which they paid.

Prices
