What contests are launched now in Free TON?
For this question, I think you are better to ask on their telegram group if any. Usually, an event or contest will be announced on telegram channels or chat groups. You also can directly ask the team or TON management if you ask directly to them. It sometimes will take a long time to see their answer if you post your question here.
I already gave him an answer; whenever contests come up we'd post them here and update everyone. Then your suggestions are still great he can check on the telegram group and on the contest board on the forum as well to know beforehand.
