Eternal Bond Invitations

This might be a difficult thing to do, but can you please make it so that when we send someone an invitation to our wedding, that it becomes bound to the receiving player somehow?

I'm asking because I've found out its possible to give someone an invite and then that person can trade the invite I've given them to another person. A person whom I had not invited. Now granted I did intend to give the person who ultimately received the invite an invitation myself, but this is not a good thing if people you don't want in attendance or strangers are getting invites passed to them without consent from the wedding party. It is after all a special day and Id rather not see it ruined by a stranger that was never invited.

Well at the same time this makes it possible to send someone an invite by proxy since you are having probs trying to be online at the same time as them due to whatever reason.

Maybe a better approach than locking it down to not be tradable is to tie it to the character by name(and of course by id on the backend).
