Invitations gathered up at points to be dished out (11)
I believe the answer is:
temptations
'invitations' is the definition.
(I know this)
'gathered up at points to be dished out' is the wordplay.
'gathered' becomes 'met' ('meet' can be a synonym of 'gather').
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'to be dished out' indicates anagramming the letters.
'met' backwards is 'tem'.
'at'+'points'='atpoints'
'atpoints' anagrammed gives 'ptations'.
'tem'+'ptations'='TEMPTATIONS'
(Another definition for temptations that I've seen is " evil desires".)
