It seem that the forms are given a .doc ending when you try to open them. This will not work so for now you will have to right-click on them and save them with just the .xls tag.

Team Entry (for team administrators only)
It is recommended that teams sign themselves up. By doing so, they can enter in what their team colors are, they can add players to their roster, they can upload their team logo, and they can select which division they would like to play in.
Teams
To create a team you must first be registered, confirmed and logged in. You will then create your team which will have to be confirmed by a league administrator.
Rosters
To assign a player to a team's roster, the player must have first created a user account on the website. Team representatives and league administrators can add players to a team's roster by going to the Teams page and selecting their team. On the team view page, you can enter in a player's name or email address which will search for that user in the database. Once a valid user is found, clicking Add Player will add that player to the roster.

Players
Players can register and then request to be added to a team by clicking on the Team link to the left and then choosing the team they wish to sign up on.
