What do I do if I already registered an account with zoho and got the email about using my google groups one?

When the jquery group was imported here I went and made a zoho account(this one), but after two days I got an email telling me about the move and asking me to create an account using my google groups account with all my discussions saved.

So what can I do? can you import the posts from this one to that one and delete this one or just delete this one?

Thanks.
