# How to solve a sudoku puzzle

I. Find an empty cell
  * Starting at 0,0, scan the board looking for 0
    * Scan is some kind of nested loop! (Outer loop looking on x axis, inner -> y axis)
    * If found
      * Coordinates of first found empty cell gets stored (probably in an instance variable)
      * Move on II
    * If not found

THINGS FOR LATER

* How do reg ex match groups work? What's with the non-interpolation interpolation? Why does the match group need to be in a string? 

A la: 
def hide_all_ssns(string)
  string.gsub(/(\d{3})-(\d{2})-(\d{4})/, 'XXX-XX-\3' )
end

FAUN
* Why not use oAuth 
* Dates / times on the session RSVP section on the Volunteer page is confusing. Better text plz.
* Headers on RSVP form look terrible
* When I signed up it took me to the account page -- what do I do next? 
* Connect to Meetup should redirect back to the event index instead of to your account page
* Add some kind of flash message for "You have successfully connected your account to Meetup!"

LILLIE
* Form submit buttons need any style whatsoever

* Anyone can have a workshop. The materials are open.
