The campfire name is stackoverflow.com, a site dedicated for handling programming questions. The event details are bellow:

From: The R Flashmob Project
Subject: R Flashmob #2

You are invited to take part in R Flashmob, the project that makes the
world a better place by posting helpful questions and answers about the
R statistical language to the programmer’s Q & A site stackoverflow.com

Please forward this to other people you know who might like to join.

FAQ

Q. Why would I want to join an inexplicable R mob?

A. Tons of other people are doing it.

Q. Why else?

A. Stackoverflow was built specifically for handling programming questions.
It’s a better mousetrap. It offers search (and is well indexed by search engines),
tagging, voting, the ability to choose the “best” answer to a question, and the ability to
edit questions and answers as technology progresses. It has a karma system to
reward people who are happy to help and discourage MLJs (mailing list jerks).

Q. Do the organizers of this MOB have any commercial interest in stackoverflow?

A. None at all. We’re just convinced it is the best way to help and promote R. All
the content submitted to stackoverflow is protected by a Creative Commons

I am waiting to see who else will join the fun.
