It's pretty easy Walter. Just click on any of the boxes above, especially Questions and categories. Super easy site to use. Not many users all the time but it's peaceful here compared to some sites. Click the little box on the upper right of an answer to vote for it if you wish. You can click on someone's profile picture and you'll see a star in the upper right corner and if you click on that? You'll be following that person also. Don't hesitate to ax if you have any questions as most of the people here have been here a while.
