Right now, its not possible to quote a post from a locked topic because we cant reply. Quoting from locked topics could be useful sometimes to refer to a normal quote like its possible for every unlocked topic. I know, its also a solution to just quote the text and add a link manually but that wouldnt include the date of the quoted post and need more time to type the author, especially for multiple quotes.
That problem doesnt include only historical posts but also some recent ones like the 10-year contest from theymos where I tried to refer to in our local section while quoting it.

So, my suggestion is:
Enable quotes from locked topics and display a message that the topic is locked; people can only copy the text to use it as a normal quote but cant submit a new reply:

Is it possible to implement? Its not super important (like the new forum software) but would be nice in my opinion.
