İn this step , people are listed on the left.These are stored in a db called info bank.İt consist of people that are listed based on their corporation , title and name info. User can add new user to the list as well as to the info bank.
Participants to this event is listed on the left where to user can drag and drop from the list of people on the left.
User can group and add different participants such as speakers , singers ,security , medic exct. by the custom filters provided on the left list. Later on these people will be used for another list to get feedback to attend the event and some other conditions.
