1. प्रॉप्स are rewards दिया द्वारा other फैन्पॉप members for your contributions. Say आप added a good video, someone might give आप a प्रॉप for videos, या if आप answered a सवाल well आप could get a प्रॉप for answers.
However, people also give प्रॉप्स randomly, just stuck onto दीवार messages saying "hi" या "thanks for the add". People also give प्रॉप्स as rewards for winning competitions.
2. To give someone a prop, आप first go to their प्रोफ़ाइल and scroll down the page til आप reach the end. There, आप can post a message on their wall. आप write whatever आप want to write in the white box - no one can give a प्रॉप without a message - and click on the सेकंड little image box beneath it then select the प्रॉप category आप want. Then आप just click Post.
Ok there are two parts to this question. 1)To send प्रॉप्स आप go to the person आप want to प्रॉप्स page and click on props. A small text window will answer and आप type what आप want.
2)Props are many things; People use them to keep in touch with friends...others use them to complament others on their pictures, their stories, etc.
