Q: How to delete a post and thread from 2007

Depending on what it is, and where it is, you may ask a Host...

Do you have a link to specific post, thread, or discussion in question?

From the year 2007, I see you had authored six threads.

If those weren't locked, you could add a new reply to that

one asking if someone could ask the Host to delete it.

But since they're all locked, a user with higher standing may report any

of those and inquire of the ASC Hosts, & ask if they'd remove it for you.

They could ignore the request, or act on it. IF there a valid reason...

Usually ones that far back get ignored anyway, so why remove any?
