I must welcome you!
It's great that you have a mirror link for TOR (99% of the time it's interesting to access the mixer's features on Tor, especially due to the legislation of some countries).
I just found the 8% fee for mixing amounts between 0.01 - 0.1 BTC a little high, especially for those who just want to test the mixer. Maybe it's a good idea to offer free mixes (first mix free), especially for you who are going to start a signature campaign in a few days.
I'm sure you chose a trustworthy and extremely professional manager! AB de Royse777
