Where is the code located in the plugin that specifies the weekly digest option as 7 days? I'd like the option of sending the digest every two weeks instead of every week. Ideally, there would be an option to designate number of days, in addition to the current options -- but for now I can live with hacking the plugin or adding some code to my theme's function.php file. Can you help me out with either identifying the file and location where I can change the 7 days to 14 days, or in writing the code I could use in the functions.php file to make the change? Thanks!
