Step-by-Step Corrections:

1. "thinks" → "think"
- Subject: "People" (plural) → verb must be plural: "think"

2. "thing but they are not." → "thing, but they are not."
- Add comma after "thing" to separate two independent clauses

3. "editing means..." → "Editing means..."
- Capitalize the beginning of the sentence

4. "Some Examples" → "Some examples"
- "Examples" is not a proper noun; lowercase

5. "runon sentence" → "run-on sentence"
- Correct hyphenation: "run-on" is a compound adjective

6. "corecting" → "correcting"
- Spelling error: missing 'r'

7. "does nat involve" → "does not involve"
- Typo: "nat" should be "not"

8. "incorrect punctuation?" → "incorrect punctuation."
- Question mark is incorrect here. This is a declarative sentence, not a question.

9. "proofread is the last step" → "proofreading is the last step"
- "Proofread" is a verb form; we need the gerund ("proofreading") to act as the subject
