In the 1st tutorial it tells you to click on the gear wheel icon and let Sven become a hunter. If I click on huntsman it just goes to a description of the huntsman's tent. I don't know what to do.

You should have to make him a Hunter and assign him to work in the huntsman's tent. I did it by right clicking on the Viking then clicking on the assign profession and assign workplace icons what comes up.

Yah, I had a dang hard time figuring out that when the tutorial says click, it means right click. Tried this game hungover the first time, wanted to scream... :D
