I have just noticed this thread. The mixer is not very known, as i didn't see it being suggested from others despite it is running well since a considerable time.
This is why i would like to repeat the ask about promoting it. In first replies, a user suggested you to run a signature campaign here in bitcointalk, and your reply was that investors want to reserve the pool amount to run the mixer. It was long time ago. Don't you still thinking is presenting the service in social platforms will help in business growth?
The user count has risen again, but also the number of support requests is higher than usual.
Not due to problems, but due to the uncertainty if everything is alright with the service.
The answer: yes, it is!
Sorry, I can't figure out this point?
Did users contact support before to use the mixer about their uncertainty if the service is all right? If yes, then you think that your answer is sufficient?
