you think doing this could compromise future updates?
and for sharing themes and plugins is changing qa-base.php like this fine?
define('QA_EXTERNAL_DIR', QA_BASE_DIR.'../../qa-shared/qa-external/');
define('QA_INCLUDE_DIR', QA_BASE_DIR.'qa-include/');
define('QA_LANG_DIR', QA_BASE_DIR.'../../qa-shared/qa-lang/');
define('QA_THEME_DIR', QA_BASE_DIR.'../../qa-shared/qa-theme/');
define('QA_PLUGIN_DIR', QA_BASE_DIR.'../../qa-shared/qa-plugin/');
