How to chat on google talk?

In google talk/gmail chat, how can you tell if someone ignored a chat invite?

• Here's why I ask: I know some people have deleted me from chat and they show up with nothing next to their names; others show up as invited, and still others (who have blocked me) show up with a gray circle. If someone ignores your chat request, does the name disappear? I know someone accepted it, but it never showed up, then, it lets me 're-invite' the person, and each time it's been accepted, it disappears, while others, continue to show up as invited. I hope this makes sense.

• Answer:

  Yes, If they don't accept... their name is removed from the list.. I'm not 100% sure but, I believe if you go to your sent mail the invitation will be there...
