is there anyway to delete a question in this forum instead of just editing it?
How to delete a question posted in this forum?
No.
(At least, not for users of the Forum)
Do you have a question you would like deleted? The mods should be able to do it if you share the link. However, if you want this as a feature, I would suggest filing a feature request on feedback assistant.
User can edit question, but only during one hour. After it is frozen, no way to change anything.
A way to alert moderator however: report an issue on the question, clicking the circled exclamation mark and select "Other category".
But you cannot explain what the problem is.
