If your group was worth of something, you'd be charging real fees. Periodically.
And why is that? Give me a concrete reason why should we charge members let's say 1.5 BTC a month?
The whole point of the one time fee is to get serious people in and then decide within a 30 day period if they are worthy to be members of a group of EQUALS.
Who would you be paying a monthly fee to if there is no leader? You would be paying a fee to yourself which is absurd and complete non-sense.
