I'm writing to you from the future) the test is already in the active phase

Well I don't understand the question but I think the team will switch to tesnet when all the tests are successful for the moment Devnet works fine

When we (they) fix all the bugs and get a seemingly stable version. The rest of the errors will be corrected when testnet launch. And you will ask "sui when you will switch to mainnet?"  

How to @ping Sui developers?? ahahaha
