Friendly suggestions

Ok, so I saw @datachomp open this project up.  I took a look, and I thought I'd throw in a few suggestions.  

I did this while watching tv, so don't trust everything... my attention was spread out.  

This line:

```
.joins(:venue).select('agendas.*, venues.venue as venue_name, venues.map_link as map_link').find(params[:id])
```

Active Record does all of that work for you, *except* the flattening of ```venue.venue``` into ```venue_name```.

It's like... you already sold your soul to the devil when you decided to use Active Record... so why not have some **fun** with the money while you can????
