In our forum, we’re looking into automatically locking old topics. Topic resurrection is a particular annoyance for us because we have a long history of mailing list traffic that’s been auto-converted into topics. However, there’s an unexpected complication, which is that there’s no easy way to quote posts from locked topics — you can link to them, but you can’t do a linked quote because the only way to do that is the Quote button (and then c+p into the new post), which is disabled in locked threads (for non-admins). The best you can do is a c+p, which loses the semantic link to the old post (and possibly at least some of the formatting?).
Is there a way we could allow Quote to work, just with some visual feedback that actually posting is disallowed?
