Hello I have a question, they could still signs a program. What is worth indicating some that you know about then that amount to an account. Then a sign where you can withdraw again, but again must specify the amount. But one would have to hold still can create account, number of accounts should be able to edit in the config.
Would that work or do I have to look for someone else?
