The Gift from Italki

Yesterday, I received a letter of advice notification from the Post Office. There was a message that I hadve to take pick up [=collect] an envelope. I did not realize that it was from Italki, but after I read who had sent the envelope [=package, packet], I decided to go to the Post Office to take collect [=retrieve, pick up] my gift. Of course, I had known what would be into the white envelope. It was a t-shirt that is given anyone who has taken a part [=participated] in the New Year's Language Challenge. The rule was following as follows: a student hasve* to take 20 lessons within several weeks, if the rule challenge** was performed met [=completed], the student will get 400 ITC. Moreover, they sentd me a t-shirt and a pen. It is really nice.

Crongratulations on the nice swag! :D

*Student is singular, so "has".

**"Challenge" is the appropriate word to use here because rules imply an ongoing "thing" that is followed, not something that is followed and completed.
