SK-welcome aboard and BOL! I will look forward to seeing your picks in the future.
To answer your question, if you go to the top of your screen, you should see a row at the very top, in blue shading and blue lettering. Up there, click on the tab that says "Settings"
Then, just a little ways down the page, there is a question that asks if you want to include your record in the signature line followed by a box. Check that box.
Right below that, there is a row of options asking you to check the time period you want measured. Check whichever one you want. Then, go to the bottom of the screen and click on the blue box that says "Save Signature." That's all there is to it!
To make sure your bets are recorded, click on the box that says "Make Picks" at the top of the page, next to the "Forums" button. Then, go the game, click on the line of the respective team you want to bet, or click on the total, either Over or Under for your particular game. The site will automatically update your record overnight.
Hope this helps. BOL!
