I am loving STM so far..
Hi 
welcome to STM, I believe you will enjoy all the valuable info you can gather here with us, and of course we will be happy to hear the info you can share from your own experience 
If the affiliate marketing is all new to you, in my opinion for start you can aim to find out what verticals are relevant for you and learn about promotional methods & traffic sources.
Wish you best of luck and looking forward to hearing about you planning the next campaigns.
