can you guys add in the game where you can add a friend back that was deleted, i have mistakenly deleted one of my top best friends and i now she is gone forever, please can anyone help
The only way to do that would be to find them again, if you have another friend that was friends with them also I'd start there. See if they can arrange a meet up so you can friend them again.
Try posting for them at Wizard101 central or here on the message boards. As a last resort you can try going cycling realms at the bazaar or the commons and ask if anyone has seen them.
