There are 2 ways for a 1-1 chat to occur, personal request or general request (GR is often used here).
For a personal request a member picks the listener. They go to a listener's profile and click chat now (listener status is online) or leave message (listener status is busy or offline). If a listener has their status set to online they are more likely to get personal requests and in browse listeners they appear above busy and offline listeners.
If a member doesn't see chat now/leave message when looking a listener's profile it's because the age groups are a mismatch. There is also no way for a member to have a 1-1 chat with another member.
For general requests a member sends out a chat request by clicking chat with a listener and optionally selecting a topic. Listeners can see a queue of these members waiting to speak with a listener and can select a member to chat with.
