@Technomage can we edit/change our guess till the deadline (19th of December 10:00 UTC), or once post it, is final? (not stated in the rules, hence I am asking)
We have updated the rules in this regard and the answer is no, the price guess can't be changed. The first guess is final. Fixing errors or typos in the comment is allowed but not changing the EUR amount.
Here is the updated rule that I added to OP:
- Modifying your comment afterwards to change the price guess is not allowed. Fixing a typo or a clear error is allowed, but changing the EUR amount will lead to disqualification of that participant.
