Do you have a system for translators to submit their opinions about whether the client is punctual in making payment to the translators?
That's a great suggestion. We don't have anything like that at the moment, however, we do have a dedicated forum thread for this called Late Payments & Payment Practices. You might post your questions in there, and hopefully other members of our community will assist you.
If you're a member of our community, you can create a new thread here: https://forum.theopenmic.co/t/late-payments-payment-practices
Simply click Start a Discussion button and create a new forum thread.
If you're posting on our forum for the first time, make sure you create a forum account. It's easy. You can either click Login with WordPress and use your Open Mic's account login and password or you can signup via Facebook, Twitter or email.
Let me know if it helps.
