 * Hi Chris,
 * Could you share how your plugin affects my WordPress database?
    1) If if add 
   extra database tables, what are they? 2) If it modify core WordPress database
   tables, what are the affected tables and what are the changes? e.g. 1 related
   post plugin actually changes wp_posts table’s database engine from InnoDB to 
   MyISAM 3) Does it simple add records to WordPress core tables e.g. wp_options,
   wp_posts, wp_postmeta etc.?
 * Thank you,
    Eric

 * Hi Eric,
 * It only uses standard WordPress post meta. No custom tables or db changes.
