I'm Ryan, a Computer Science student from the National University of Singapore. I want to participate in GSOC this year, and after going through the list of organizations, I'm particularly interested in LimeSurvey. Among the project ideas found on http://docs.limesurvey.org/Project+Ideas+for+GSoC+2012
, the first one "Refactor all question types to a modular OOP format" interests me the most. May I know where can I get the current documentation of LimeSurvey architecture so that I can get myself familiar with the system? I'll get to work on my proposal as soon as possible.
