I second the statement above, as I’ve been a testnet member for over than 2 months already.
Firstly, it’s really a great playground for validators to learn to deal with things in unexpected consequences and therefore be more prepared for things going wrong way on mainnet.
Secondly, it’s also a great way to see the features that would soon land on mainnet beforehand and know what’s coming in the future onto a mainnet and how to use it.
Lastly, I cannot say anything except the positive things on how the whole thing is coordinated, both from Hypna’s side (as they were extremely helpful and willing to listen to validators’ suggestions on improving the whole project and also willing to help those in need) and from validators’ side (everybody is super helpful and I’ve seen a lot of validators helping others in need).
Happy to be the part of it and hope some of my support was also helpful. Way to go, guys!
