Early [draft is up at hackmd](https://hackmd.io/xXSEti6KRMCpERineQMMnQ), haven't put it up on the blockchain yet since I am seeing it it's appropriate as a utopian.io tutorial first. Also sent you a pull request with my edited cpp file.

I noticed :) This statement ```if (0 != event.mc())``` is not necessary. You are not using at all the ```event.mc()``` properties. You may however want to add a protection (in case of an empty event record). In this case, you should use: ``` if (event.rec()==0) return true; ``` Hope this helps!

Nice catch, that's what I get for looking at some of the example code in the comments. At one point, I *was* calling `event.mc()->processId()`, so I could've justified it. Which leads me to a question, I was getting all 0's for processId, do events have unique identifiers?

We have a unique data format dealing with many event formats. According to which class of event you have, some of the options may stay empty. I hope this clarifies.
