You can count on me for the testing phase... You might want to also consider disclosing the link in question while having a limit of 50 for the sign-ups [less effort = more responses]!
1. Honestly you'll have harder time looking for tester since not everyone have testnet coin. As for myself, i returned few micro tBTC to faucet where i got tBTC after i done experimenting with LN few years ago.
2. Since it's not easy to obtain tBTC in big quantity, you should specify minimum withdraw/deposit amount of your exchange.
If I'm not mistaken, I had about 0.07 tBTC lying around ... I would gladly take part in the testing, but for the next few days I will be busy for obvious reasons. So if any of you are interested, write to me and I will give you a private key from my tBTC
(and you will share with others if you wish).By the way, here are a couple of useful links ..
