You can only have 100 friends – and honestly, if you visit them all every day, it gets tedious before you even get to 100!

If you find that you can’t add more friends, you may be at your maximum (check your friend list and see if you’ve reached it). If you’re adding someone from the Facebook page, it’s also quite likely that they’re at their maximum, so you won’t be able to add them either. Just move on down your list of invites and add who you can.
