In My Q&A, there is a function where you can view your questions and answers. Under questions you can look at all the questions that you asked. To vote for someone else's answer as a best answer just click on the button to vote for them in the question and answer page. Usually the ones that are most detailed and offer an opinion are the ones that I choose, so hopefully you'll get to choose me :)

Comments are shown when the question has a best answer already, you can leave a comment (it says underneath the best answerer's avatar "Add/View Comment") and you can just comment on that person's answer.

If someone says something rude, all you have to do is click on the "Report Abuse" link next to their answer. If someone asks you a question on the other hand, the only possible way, so far, to answer their question is to click on their username and see if they have a link on their profile that says "Contact *username*"

If you want the points rather than giving it your honest thoughts, just pick an opinion-based question and agree with whatever nonsense the questioner has put up.  For example, somebody may ask "I think we don't see enough pink sparrows, don't you agree?"  Answer, "Sure, I would love to see more! Great idea!"

You click on the light blue box at the bottom of the question that says "Answer this question" I have not posted a question so have not replied to an answer, but it can be done and I think it is probably pretty easy. Look at the whole screen.

Go to your original question and click on the answerer's picture.  That will bring you to her profile.  From there you can click on one of her questions and just thank her through that.  I am assuming you have resolved your question and picked them as the best answer - you are able to write a comment about their answer when you choose a best answer.  If you already chose a best answer but did not let them know I think the only thing you could do is go to your original question and click on the "add comment" icon and write something there hoping they will read it IF they even go back to the question.  Helpful?  Hope so.

You can't really, you can only leave one comment on one person's site at once as far as I know. Sorry.

No there isn't a way.. you can post a question asking others to answer your first question. Ive seen many do this

You may be able to edit your question, that's how many people respond to some of their answers. This would allow everyone who views your question to see your edited responses. For a personal reply to a specific person, follow the directions of the previous answerer.

Bear in mind that these are nicknames and not email addresses.  If you want to acknowledge answers to your question, a popular way to do that is to add additonal comments to your question.  Another method would be when you choose a best answer (as opposed to putting your question to a vote), you can post a reply to that user and to everyone as well.

You can add a comment even after the question's been resolved. That way you can clarify your answer.
