Hello Samuel and welcome to steemit.
A requirement of this contest is to use the #happystream service (it is free and needs more users to know about it). I see you have not made a post in the past week that you could use to promote, but you could promote ANY post or if you have a service to advertise or something you wish to buy, sell or give away, you could use that. It is very easy to get your guess qualified, so please complete the requirement to have your guess count in the contest. Thanks!
Probably the BEST resource for you since you are just getting started is the wiki that has a LOT of information in it. Here is the link: http://www.steem.center/index.php?title=Main_Page
Probably a good idea to bookmark it.
