## Reactions to "Edelspam"

In our first Editorial, Lennaert van Veen brought up the issue of academic phishing, bogus conferences, pushy publishers and other highly targeted spam we face in our profession. In particular, ICIAM TV was mentioned as an example. Tony Harkin of the Rochester Institute of Technology comments.

## Massively Multiplayer Mathematics

Although theorems are frequently named after a single person, most progress in mathematics is the result of a group effort. Recently several difficult problems in mathematics have been attacked by a collective of mathematicians that have communicated through online blogs. The immediacy of this mode of communication allowed the first proposed problem to be cracked in a surprisingly short time. Will this remain an isolated approach, or can we expect that hard mathematical problems will be regularly crowdsourced in the future?
