Begrudge being posted again (6)
I believe the answer is:
resent
I believe this is a double definition.
'begrudge' is the first definition.
('resent' can be a synonym of 'begrudge')
'posted again' is the second definition.
('sent' can be a synonym for 'posted' so perhaps 'resent' is OK for 'posted again')
'being' is the link.
(Other definitions for resent that I've seen before include "Feel indignation at" , "Feel aggrieved at" , "Feel bad about" , "Don't like" , "Feel bitter or indignant about" .)
