I would quote from pinned closed topic that refers to the rules but i can’t do that anymore without actually having to edit in the topic id and user name into the quote syntax myself in the composer.
[quote="name, post:1, topic:1234567890"]
[/quote]
It started happening on the update when the font changed and the quote button was made smaller
It looks like historically we have had the behaviour described by Justin above, i.e. a non-admin user can only quote a closed topic if they have an open composer. IMO we should simplify this and display the Quote button on closed topics without the “composer must be open” requirement (and when invoked, the composer would default to creating a linked topic).
