Welcome to Fusion Cash!
You found the Forum. Always a good place to ask questions and get some answers.
Your question is wide open. I suggest that you go to the Support section of the Forum and click on Beginner's Guide (one of 2 threads at the top of the page) and read through it. It will provide you many answers to the basics.
Also helps to read the Terms of Service.
Click on the Offers link at the top of the page and then the Daily link towards the top right of the landing page. That will take you to the daily click (worth $.15), the signup box for the daily email (worth $.02), the video ad box, the Radio Loyalty offer and all the daily surveys.
Amounts credited to your account expire in 180 days.
You need a minimum of $15 in offers and $25 in total to request a cash out. The $5.00 bonus you received is a BONUS, not an offer.
(When you reach the $25/15 requirement wait until towards the end of a given month to cash out, because cash out payments are made around the 20th of the month FOLLOWING the month you make your request.)
Once you read through the Beginner's Guide, read through some of the forum entries about items you still have a question about. If you don't find enough of an answer, start another thread and ask your question(s). Try to be specific -- explain what you understand and what is unclear.
The more you tell us, the better we can help you.
Oh! One more thing. Look at the Contests and Promotion section of the Forum for a description of the Posting Bonus and the 2 mini weekly contests as well as the other Bonuses that are available.
