I have found several questions about chatting with low-rep users, and the answers usually mention making the user visit chat so that you can invite him to a room. My question is, does just opening a tab to https://chat.stackexchange.com make someone a chat user, or does he need to visit a room, visit two rooms, ... What counts as visiting?

To create a chat user you need to log into chat. For users logged in to Stack Exchange, that is done automatically (they get logged in to chat automatically).

Visiting rooms anonymously will not do it, as anonymous users can't do anything on chat.

The chat faq has this to say:

How do I join or log in?

You must be a registered user of The Stack Exchange Network to participate in chat. If you are logged in there, you will automatically be logged in here. Your display name and gravatar are also inherited from The Stack Exchange Network.

  • But what if he is already logged in on Stack Overflow? Does just visiting chat make him a chat user?

  • @zondo - I clarified - yes, that should be the case.

If you want to invite someone to chat, the only single requirement is for that other user to have 20 reputation points.

The chat profile is created when anyone visits it, on the fly. For example, I've just vitied this chat profile and it has been auto created on spot: (the user is member of MSE for over 6 years)

Note I can't invite him to chat though, since he got less than 20 reputation.
