Guarantees two points to new users (7)
I believe the answer is:
ensures
'guarantees' is the definition.
('ensure' can be a synonym of 'guarantee')
'two points to new users' is the wordplay.
'two points' becomes 'en'.
'to new' is an anagram indicator.
'users' anagrammed gives 'sures'.
'en'+'sures'='ENSURES'
(Other definitions for ensures that I've seen before include "Warrant" , "Makes safe or certain" , "guarantees" .)
