Are unlisted threads deleted?

Are unlisted threads accessible to the person who started the thread? I had a feeling they were but I can’t find a thread I started a week or so ago.

The thread concerned an issue where an update to dmxFormatter.js had broken some functionality that had always worked previously (it was a matter of the order in which dynamic events were added). The thread was unlisted. I have come across a similar problem which I’ll probably mention in a separate thread.

I notice that dmxFormatter.js has been updated several times recently; it would be useful to know which version caused the problem when I raised the issue.
