Hi there!
Actually yes, the Mantis is available. It is odd you did not get the confirmation back.
If you are still interested in this, please drop me a private message so that we can work it out.
As for the Community feedback, trust me, we care about it and we read it. However, we do not have enough time to reply in a timely manner.. for which cases we suggest getting at least a basic subscription so that our Support Team can get back to you ASAP.
Best regards,
Francisco
