I am currently in the process of writing a running commentary on a PBEM game. As the game is still very much alive, I have been unable to post the stories, and they are piling up far from prying eyes. When I do make them readable, I intend to give each story a specific "post date" seperated by perhaps one minute. That way I can determine the order of the stories and have them show up nice and sorted. You don't have to set the date to the future, so you can retro-actively fix it - unless you have lots of stories. Tweaking the "post date" is much more attractive to me than hacking lib-common.php, as future upgrades of GL are sure to overwrite it, and keeping track of various changes could be a daunting task.
GL is very flexible if you use the parameters creatively.
