You are most welcome @upheaver and thank you so much for your comment. I would be honest with you, the reason I did not try selling votes through MB that much was because I could not track my votes if they were going to high quality content creators or not. Now thanks to white-list and this feature, I do not need to worry about that. Now I will freely use "Vote-Selling" service with "Whitelist-only" mode ON. ;)
There is still one thing that I could not figure out - Where can I track the applications of people I invited? This would help me to know where they are getting stuck!
Yea can on your user page see your whitelist history. Your personal page only you can view is: https://www.minnowbooster.net/users/hungryhustle/whitelist_activity_list
Thanks for the pointers @reggaemuffin. I see the history now. Thumbs Up
