Merge/Delete Account, Reuse Email Address

While trying to link my Facebook, Twitter, Google, and OpenID accounts to my Get Satisfaction account, I inadvertently created a second account, as the interface for linking accounts is anything but intuitive (and there's no way to review current linked accounts).

I deleted my second Google-based account, but I now am unable to add my Gmail address to my original Get Satisfaction account. I'm told "address has already been taken".

I would like to either delete my Google-based account so I can add my Gmail address to this account or have the two accounts merged.

Then, I would like to request a good interface for managing linked accounts for logging in. It's currently impossible to review the OpenIDs attached to my Get Satisfaction account, for example. It doesn't seem like anyone really thought this through before it was implemented, and it's an overall bad user experience. I think putting some effort into this process will vastly improve the quality of Get Satisfaction and will cut down on requests such as this one.

Thanks.
