Welcome to Geeklog Sunday, May 01 2016 @ 07:09 PM EDT
Once you have your Geeklog site up and running, you'll probably want to customise it a bit to better suit your needs and preferences. The first place you should be looking then is Geeklog's configuration file, config.php.
config.php contains over 100 configuration options, mainly for those things that you won't be changing too often (that's why there is no web interface for them). The comments next to the options as well as the documentation should get you started.
