Set up info is at slackarma.gaberoeloffs.com.
This is the source code of Slackarma. I hope I commented it enough so that you have at least an inkling of understanding of what I'm doing.
Slackarma uses Postgres SQL, only because Heroku told me to use that. If you want to get the project running locally, you'll have to install Postgres on your machine.
Most of the important code resides in routes/index.js and in the models folder.
Speaking of the models folder, to set up the table for Slackarma, run the command
node /models/database.js. This will create the table.
As long as your PR doesn't contain malware or PHP (same difference I guess?) I will probably accept it.
