This challenge is called "Filling the gap" and this is how it works:
In the forum, I will put the username of a previous C&A player. However, I will leave an empty space anywhere in the word.
You must reply with the missing letter or number.
Example:
CHAN * ELIER
Answer: D
If you are the first to answer correctly, you will score 1 point for you.
The first player to obtain FIVE points will earn immunity.
Any questions?
