Michael,
We’re still waiting on the developers to implement the ability to merge user accounts so that we can clean up “split head” user accounts like yours.
As to the account’s “Created” date, everyone’s account creation date was set to the day that it was imported into the new platform (the import was run over the course of 3 or 4 days). I have asked the developers if there is a function to change this value.
In short, my answer is (still) “please bear with us”.
