Questions: What's required to vote for answers?

[Acid Bubbles]

I noticed that:
- I cannot vote on an answer (see 1st screenshot)
- I can post pre-answered posts (this may be fine, StackOverflow allows this, see 2nd screenshot)

I have voting fixed. You can also vote on your own question, and you are welcome to pre-answer and mark your answer best.
