I'd be curious to know how many of the registered users have let their balance run out and not topped it up.
Also, it would be useful to be able check and see if a member is registered to see if your potential dust vote would be save or wasted, or for running contests where you want the winner to be a new user.
I did a quick check and it is around 35 users with that haven't topped up.
I'm hoping we can have the Discord server up soon. There you will be able to search for users and check balances etc.
35 out of over 600 is a pretty good retention rate. Less than 6%. Well done.
