Staff comment on website? (4)
I believe the answer is:
post
I believe this is a double definition.
'staff' is the first definition.
(thesaurus)
'comment on website?' is the second definition.

(Other definitions for post that I've seen before include "Part of address" , "Spot the mail" , "a placement: it's > part of one's goal" , "ob" , "A column" .)
