More than one picket comments on website (5)
I believe the answer is:
posts
This clue is a double definition.
'more than one picket' is the first definition.
(a picket is a post or stake)
'comments on website' is the second definition.
(as in an online post)
(Other definitions for posts that I've seen before include "a couple seen propping up the bar?" , "Positions, for guards say" , "Stakes" , "Sends by mail" , "Mails the uprights?" .)
