What is the recommended way to re-open a discussion (for example on the topic of what is considered off-topic)? Some discussions have one or two comments, but disappear from the main sites after a while before a decision is reached. Some issues might even need re-consideration because the circumstances that lead to a decision have changed. How can we re-open such discussions? Just posting a new answer or comment won't always get it the attention it deserves, but posting the same question again also seems weird... Any Ideas?
Just post a new question and explain in the question that while there is a duplicate it is different and why you think it needs to be discussed again in a separate discussion.
We aren't as strict about duplicates here on Meta. We usually suggest though that if you're opening a new discussion on something that you link back to the original discussion(s) for context, though.
