After setting up your profile, you'll have access to all of its features including live video chatting capabilities as well as text-based conversations in private rooms between two people or within group chats where multiple people can join in on discussions about various topics such as music, movies, hobbies etc.. Additionally there are also filters available so that users can find others who share similar interests easily by selecting specific categories like age range or location preferences if desired before starting their conversation online!
