Thank you very much for your answer, Peachy.

I asked this question a long time ago. Just wanted to know how it works :)

Congratulation for being a winner :))

Hi Sina,

Mine is already in my account, so all good there. I think it works like this: by pledging the 100ITC at the beginning, your name is added to the list of participants. Once the time for the language challenge has passed (and all lessons have been confirmed), I guess the admins go and check how many complete hours you have done, and then put 400ITC back in your account. This probably takes some time; I doubt it's automatic.

I'd kept a separate tally of my lessons anyway, just in case there was any confusion. If there are any problems, of course you can write to the admins, but I'd still give them a few more days to check every participant's tally.

I don´t know anything about it.
