Link topics after they have already been closed

Pretty much what in the subject.

As a user I would like to have the ability to link related issues. Items dealing with the same subject, or one has answered the other. There is this kind of feature on Jira, GitHub, StackOverflow among others.
The user could link the issues and submit to a community moderator to review and approve.

When the topic still open it’s possible to reply, adding the link to another issue. But when the topic is closed, it’s not more possible to do it. In this case, a topic keeps without a solutions even if it was resolved on another one.

Not exactly the answer you are after, but keep in mind links in Discourse are bi-directional.

As long as you link the destination to the source, the source will have a link to the destination.

So you could use an open topic to link up the closed topic.

Yes this is already built in, and has been since 2013. Let me illustrate by linking another topic here.

When personal messages are disabled, can users still message a group?

We’ve disabled personal messages because we don’t want users to be able to message each other individually. However, I think it could be valuable to make mentioning and messaging groups to still be available. For example, let’s say we create a group for all attendees of a particular event. We’d want to be able to message each other before and during the event + notify everyone by default when a message is sent, but then the event ends and it’s no longer needed so having a private category seems …

All I did to create the above was paste in this link like so

Now watch what it looks like on the other side…

… see the bidirectional link at the bottom of the post? This works for any post in any Discourse topic.
