You should be able to edit a post until the first payout. When the payout has occurred, you can't edit it anymore.
I'm not sure but I don't think there is a way to delete anything from Steemit.com (at least it's impossible to delete anything from Steem blockchain – it's a blockchain, after all).
Usually it's not a good idea to post same thing many times. Other people might think that you are just trying to fish more upvotes by continuous posting.
Your explanation seems plausible so I removed my downvote.
Yes I'm sorry but I didn't found a way to delete the first article where I misspelled the tag. Thanks.

Thank you, it will never happen anymore. You have my word.
