I looked all over SE Meta and couldn't find a definitive answer there or via Google, so hopefully one the more seasoned SE users knows this. Is there a way to move a comment thread to chat once things start to get chatty/off topic? Is it buried in the site interface somewhere? Is it a mod-only action?
I know a suggestion kicks in once the size of the thread to get too large, but I'd like preemptively do this before the suggestion happens.
