It is possible to add an entry for another member. Once you have their email for their account, you can add them by going to the commissioner console --> member management --> add members. They will have their sign in once you have them added.
We recommend creating them an account if they do not have one already. Each member needs a unique email address. (please note the username is also going to be their email address)
Or you can add them by clicking, "Create Another Entry" under your personal picks. You can edit the entry name to whatever you wish (three dots under options). This is not recommended since there is no public link for many pool types.
