question about logging

I see back in roughly 9.50 or so, "logging" was put in place.
How is that used?
I've logged in as administrator and looked all over the place and see nothing about logs, logging, enabling logging, WHAT gets logged, etc.
How does the logging work - how is it enabled - but more importantly, WHAT gets logged?
Thanks

9. includes/setup_options_inc.asp - updated to allow the enabling of log files
40. functions/functions_common.asp - added new function for forum logging
41. register.asp - updated to add logging for new registration and moderator profile editing
42. new_post.asp - updated to add logging for new topics and replies
43. edit_post.asp - updated to add support for logging
44. delete_topic.asp - updated to add support for logging
45. hide_post.asp - updated to support moderator logging and fix forum statistics bug
46. show_post.asp - updated to support moderator logging
47. lock_topic.asp - updated to support moderator logging and added new statistics updating
48. pop_up_IP_blocking.asp - updated to support moderator logging

Ah, so it's not in the control panel area.
That's fine - my FTP app will let me open and view or even edit files directly inside the app...........

Thanks - I'll look for that file....

At a rough guess I would say welcome to the club of some people trying to inject coding

The good news is though that you can see the IP address (as in my example above) similar to your own, and in your case the IP is logged from China, and funnily enough so is mine
You could just add the IP to your banned list or just rejoice in the fact that the software is great and whilst these people tried injecting malicious code into your forum it failed
