Greeting my new team members on the same day they join - without fail.
In my welcome note I do explain how to collect VersaPoints and advise to not fail working through the daily to-do-list and their launchpad - but one each day only.
I do emphasize that they should try to collect 500 VersaPoints within their first 24 hours in SFI in order to get the "fast-track" extra 500 VersaPoints and badge.
