I agree with the value of having a setting that allows us (as admins) to create frozen slugs.
@Stephen’s solution was to disable the ability to let some users update their titles. But I find that letting the users improve their titles is a good idea.
Even as an admin, I reorganize info and retitle things all the time, so I don’t think “not renaming titles” is a good solution.
Alternative ideas
as an admin it would be incredible to be able to determine a slug for a posts. That way even if the title of the topic changes, the slug remains short and simple.
This would of course be an addition to the current 301 redirect, since after experimenting with it I realized it does work as long as the /[#number] at the end of the URL is kept.
I second @Terrapop’s request, I think it’s a great option to give to admins and avoid problems long-term
Thanks!
