Replying to Delete Button?

I think the NS should create a delete button like so if you make a post and spell smothing wrong (I do this a lot) or say something that you regret saying after (I do this too, worst was my comment to Timotheezy. Istill wish I could take it back) you should be able to delete it. I also think you should be able to delete your old threads too without having to message a MOD and comments in your feedback that you make your self and can message a mod about deleting comments in your feedback that other people made and they can decide to delete it or not (It wouldn't be fare if you could delete others comments in your feed back because then you could just delete bad ones that are true) .
