How do permantly clear a chat history? The history does clear temporarily, but if you view history again it’'s still there.
use the explorer, go to "%USERPROFILE%\Spark\user_USER_\transcripts\ (make a backup) and delete whatever you want to delete. Maybe you have to exit Spark to do this.
Can I do it automatically?
as I said I don’'t know if one must exit Spark to delete the logs.
I assume you can write a simple .bat or .pl script which deletes the logs for you.
You may call it either after reboot by creating a link in “Programs/Startup” or go to “Start, Settings, Control Panel, Scheduled Tasks” and create a new one.
