Just received an email that the PointBooster, where you guess how many trips you will take in M and C/Y in a period will earn you extra points. (300 extra for M and 2000 extra for Y/C), is back on. This time the period is between 1st March to 31st May and they need the guess by 12th February. It states that the invitation is personal and the url indicates that as well. Keep an eye out on your emails.
