Meeting in favour of you finally having minutes (5)
I believe the answer is:
forum
'meeting' is the definition.
(forum is a kind of meeting)
'in favour of you finally having minutes' is the wordplay.
'in favour of' becomes 'for' (being for a particular cause).
'finally' indicates one should take the final letters.
'having' means one lot of letters go next to another.
'minutes' becomes 'm' (common abbreviation).
The last letter of 'you' is 'u'.
'for'+'u'+'m'='FORUM'
(Other definitions for forum that I've seen before include "Meeting of people for discussion" , "Court - conference" , "Place where public discussion is held, as in ancient Rome" , "Online message board" , "Public meeting-place for open discussion" .)
