Hi, I am going through the code base (related to mdb) for last two days , but I wanted to know keeping GSOC in mind do I need to focus on research part more (and to go through most of the code base after proposal submission ) or do I need to get in touch with the code (keeping research part after submission ). Regards Jayesh Hathila
