Sponsors wishing to sponsor a specific team will also have their name and logo (with embedded link to your website) on the teams page.   Sponsors must provide an electronic copy of their logo (Jpeg or BMP) and website to be setup on the website.

In the rare case that it happens, if a single team has more than one Sponsor child associated with it, the league will place the first received and paid sponsor on that team.   We will place additional sponsor's on available teams within the league.
