Well it is relatively new as the MP app was created just 19 days ago. https://www.moneypot.com/apps/47-luckybit-micro#staff
I kinda abit lost here because I dont get what you mean. If you mean that Moneypot was launched 19 days ago then it is wrong because it was launched on 11th April 2015 (References 1 below) but if you mean that the LuckyBit Micro was created 19 days ago then it is wrong as well because the staff feature was launched 19 days ago therefore every owner and staff got appointed at that time despite it was created way before 19 days ago. I dont know exactly when Sting create the Luckybit Micro but it is more than a month already as I found it at 10th June 2015 (references 2 below)

You misunderstood my point I guess.
I knew LB has been here for more than a year. What I meant is, the game "LB Micro" is a Moneypot app (FYR: https://www.moneypot.com/apps), and
Edit: You are right, the staff page was added 19 days ago.
I just checked the first ever MP apps "Dust Dice", and it shows "19 days ago" though I know it has been around for a few month.
