I recently received an invite to our campaign page on OP, and the email was sent to what I will refer to as "Email 2" by the GM.

However, I already had an OP account with what I will refer to as "Email 1" on the website. I clicked on the invitation link in Email 2, and it said "This invitation is not for you." which I should have expected, different emails and all.

So I changed my OP account email from Email 1 to Email 2, thinking that should solve the problem, because Email 2 is where the invite was sent to.

But every time I click the invite link, it continues to tell me "This invitation is not for you." I've asked the GM to re-send the invite, but a re-send has no new link, just the same old link that is "not for me."

Everyone else has been able to join the campaign without problems, but none of them had a previously existing account.

Is there a way to fix this? A way to manually add someone to a campaign, or manually request to join a campaign myself?
