You are part of the crew, reportedly making money (4)
I believe the answer is:
euro
'money' is the definition.
(currency of the Eurozone)
'you are part of the crew reportedly' is the wordplay.
'you are' becomes 'ur' (text or internet abbreviation).
'part of' is an insertion indicator (part of the inside).
'the crew reportedly' becomes 'eo' (I can't justify this - if you can you should give a lot more credence to this answer).
'ur' inserted within 'eo' is 'EURO'.
'making' is the link.
Can you help me to learn more?
(Other definitions for euro that I've seen before include "Multi-national currency" , "Foreign currency" , "Currency of France" , "The "single currency"" , "EU money" .)
