the ASSIGN META function isn't available for comments, replies, right?well you could do it with a spintax block
{#tag1|#tag2|#tag3}
Or use the ASSIGN META function on the IMAGES tab
on the right enter your hashtags in a list
Then for the caption, at the bottom use the token
%kw% %kw% %kw%
for three random keywords from the list
so the only way to achieve it is using a spintax block?
thanks
