Q:

Is there a way to ask contributors on Area51 to join a Stack Exchange chat?

Sometimes I see somebody is active on Area 51 that it might be interesting to chat with, but it seems Area 51 doesn't have its own chat room.
It also seems there is no mechanism to leave messages on a user's profile page to say "Hey, come join chat room XYZ to talk about proposal ABC".
Are my observations right? What is a good way to initiate a chat with a user on Area 51 (assuming it's not somebody you already know)?

A:

There was an Area 51 chat room, but it was inactive long enough that the chat system froze it. I've re-opened it.
However, if it's not used for some time, it will get re-frozen.
