Here is a single team baseball website: www.AltonRedbirdsBaseball.com
Here is a multi-team baseball website: http://www.tvhsbaseball.com/ (notice the links to each team on the homepage). If you select Varsity, it will take you to a page similar to the Alton Redbirds site above.
You can purchase additional teams here: http://www.winitoathletics.com/PriceCalculator.aspx?teams=1&domain=&customgraphics=0
If you don't want to purchase additional teams, you will have to create an additional page for the other levels of your program (Manage - > Add Additional Pages) and call the page "JV Team Page"
This page will show up in the "More" drop-down and under the Important Pages section.
