Navigate to your Group homepage by hovering over "My Groups" and selecting your group. Locate the tab, above your group name, that reads "Invite Friends" and select that.
From there you will have a few different options to invite members to your league.
** Please note: Members must have FIRST created an "Bracket/Entry" before being able to join a group. For steps to create a bracket, please visit: "How do I create an entry"
1) Enter the recipient email address in the "To:" box. For multiple users you'll need to include a comma (,) and a space between the addresses as shown in the example. Select "Send Invitation" button at bottom.
2) Copy and manually send the entire http://fantasy/espn.com.... web address directly to the member you want to join via email, sms, chat, etc. Have your members go to ESPN.com, create a bracket and then click the link to join after that.
3) Have your potential members navigate to the Group Directory and use the "search" function to find the Group Name. If the league is "Private" they will need to enter the Password the Group Creator provides them before being able to join.
