How do I view answers to my questions & give points to the first person who answered it ? I asked how to put?

pictureof avatar up & I didn't even know what "avatar" was they helped me a lot,Iwant to give them points.Can I not do that one level 1? or how do I do that? Also, how do I see rest of answers? I went to My Q&A and it just said 31 answers but I can't get them. But the first one was awesome, look at me now!!
