### User's Query:
How many users who created a list in the February of 2016 were eligible for trial when they created the list? Indicate the user id of the user who has the most number of followers in his list in February of 2016.

### Extra Knowledge:
created a list in the February of 2016 refer to list_creation_date_utc BETWEEN 2/1/2016 and 2/29/2016; eligible for trial refers to user_eligible_for_trial = 1;

SELECT T1.list_followers FROM lists AS T1 INNER JOIN lists_users AS T2 ON T1.user_id = T2.user_id AND T1.list_id = T2.list_id WHERE T2.list_creation_date_utc BETWEEN '2016-02-01' AND '2016-02-29' AND T2.user_eligible_for_trial = 1
