Yes - limited editing time pleeeeeeasssee!! I keep seeing typo errors or word-repetitions, which magically only seem to appear to me AFTER I've submitted my eternal pearls of widsom.

The editing function is already there, if you care to use it. It's called "Preview".   Just check the box, and submit. You're shown exactly what will be on screen for readers.

I almost always use Preview, and quite commonly find things I want to clean up (like typos, word repetitions, and spellings, and including changing whole sections if I didn't say things clearly) before actually submitting.

Waddaya want, fergooneessakes?
