Normally the merge is done when you request it through this form: Changed Jobs?, however right now the form is down.
Also note: "Please note that we can only SWAP account information from one profile to another. We cannot merge points or profile information from multiple profiles to one profile."
Thanks, Devraj. That should work - the profile I want to merge to does not have any points or anything that needs to be saved. So as long as I can take all my information from this account and overwrite the new account, that's fine.
Is the form down temporarily or is this an ongoing issue? I want to know if I should check back in a day or two, or if this is a longer-term issue.
