This is just a compilation of commend line options you can use with GSA.  I found them scattered and collected them as I found them useful.

-deldupes
Removes duplicates from the global folders

-autostart
Automatically starts posting to active projects.  Same as hitting the start button, but it does it at program launch

-close
Closes an existing open instance of SER

-noupdatecheck
Skips the update check at startup

-delhistory
Removes the url history for all projects

-scheduler
Automatically runs with scheduler options (last selection is saved)
