Hi @arcange,
Here to me it seems you agreed to donate steemsql subscription to the winner (it's me by the way :) of ideas category. But I heard that you changed your mind after talking to favcau. free extension of any length would be great but even if you don't, I'm absolutely fine. Don't worry.
But still if you donate, it'd be great :) imho, there is a reason why the prize was introduced. There are not many good suggestions post. While I agree that idea post doesn't necessarily require steemsql in many cases, some authors like me is using it and contributing to multiple categories. Even if they haven't used before, It can also be a good incentive for them to be a long-term user :)
ps. I found a data integrity problem in steemsql: a user 'ziface18''s id is '2.2.113186' not '113186' which took me quite a time to figure out the problem in my query before :( I deserve a free subscription anyway haha :) Actually I don't understand why id isn't int type from the beginning. were you worried the situation that num of steem users grow to the moon? :) Thanks!
ps2. I'm even using steemsql for bug-hunting too! One of my recent staff picked bug-hunting [Busy] Voting percentage update problem - cause and fix used steemsql :) Thanks!
