There are two types of "custom" league types within Fantasy Football: "League Manager" and "ESPN Custom".
"League Manager" leagues are private and can only be joined if invited to play. All invitations are sent in the form of an email which contains a unique URL. This URL is the ticket to play in the league. Invites can be sent by the LM to each team and once joined each team has the option to invite a 2nd owner to co-manage the team. To accept an invitation, click the URL or copy and past it into your browser's 'Address' field. You will need an ESPN.com Member Name and Password to play. Upon a successful join, your Member ID will be associated with a team ID and you will become that team's owner.
"ESPN Custom" leagues use custom options set by the league creator which are locked upon creation. These league automatically appear in the public League Directory and can be joined by anyone.
TROUBLESHOOTING (League Manager leagues)
Listed below are examples of problems owners might experience joining your private league and how you can go about fixing them.
- NO INVITATION RECEIVED
If your commish says they sent you an invitation but you don't see it in your inbox it could be for a couple of reasons. First, the email address entered by your commish might be incorrect so make sure to double check that. Second, your corporate (or ISP's) firewall might block email from our ESPN servers. In this case we recommend your commish uses the "Send me a copy of each invite" option. Once they receive the "cc'ed" email (which contains your team's unique join URL) they can then forward that email to you with their personal email and the firewall won't be a problem.
- INVITATION RECEIVED; UNABLE TO JOIN LEAGUE
So your commish invited you to play and you got the invite but when you clicked on the unique URL... the page says you can't join the league. The reason is that your commish changed your email address after they sent you the unique URL invitation thereby nulling and voiding it. They probably did this to invite another owner to the league and didn't realize it would prevent you from joining. We recommend contacting your commish to work out the details.
