posetcay: About the previous comment, we could treat alternative answer feature as a "bonus round". When you solve the problem the first time, it gets marked as correct and you get the xp and you get offered a bonus round. If you solve the bonus round correctly, you get double xp (or %50 more). This keeps the feature fun and meaningful without feeling too punishing. Or we could also make it optional when creating the sgf, it would be disabled by default and has to be manually enabled. I personally think first suggestion is better as it is consistent with the "gamification of tsumego" goal this website was originally formed.
d4rkm4tter: We make an admin setting. It is turned on by default.
