I installed and tested this.

Z-Man, where do I see the Counter in the UI? I checked the timeline, user account settings, in the user points area etc, but couldn't locate. Please advise. Thank You.

Mary,
it's trying to implement Balamurali's request:

Read the source, turn on Ossn error logging and you'll get an idea ...

Thanks a lot Z-Man. Awesome. Will test this and let you know. Thanks Again.
