I was just wondering im not sure wether i am missing hearts?? I started with two friends i have invited others who have shown up BUT If they were already on the island and joined my family do i get hearts or is this only if they are new to the game HELP IM CONFUSED?????

You only get hearts for inviting new wizards, if they were on the island you can send gifts to each other, but no hearts.

I invited a friend to the island and I didn't get my heart for him...what should I do?

Vee, you need to request the heart. If you look at the top of the page you will see "Your Hearts [?]", click on the "?" and it will take you to a page showing all of your connections in EI. You will also see on this page "Missing Hearts". Click that and it will take you to a page showing all of your EI family with "fix heart" under the names. Click the "fix heart" that needs to be fixed. Then you have to tell the friend to check their EI profile (by clicking their name or avatar) and looking in the left column where it says "Brought by", under it in tiny letters will be a link to confirm the heart request. Your friend needs to click that link to confirm the heart. After they do that then you should receive the heart :)
