I start by saying I can’t help with the content ( even because it seems quite fulfilled now ), so I apologize if it’s an offtopic.
Now, I’m not sure if i visit the site in an update phase or something but first things first:
That said, I’m not fully convinced from the posts above: I mean, if you’re settled it’s ok - I’m this, doing this, you hire me for this and if you want something else ask someone else - but in your starting experience? For what I can read this is the 2nd client of @arhillis, is really a good thing to strictly remark your specific role and its boundaries? Obviously I will say to the client something like ‘I provided some content to fulfil the pages but I’m not a content manager,’ or so ( furthermore I read somewhere that developers are enemies of text, the less the better and is not a statement I disagree with ) but it seems an overstatement to me to refuse it at all unless you got paid or guided as a notary.
