I have a problem, need some input

I make a post out of this so the ones of you that haven't gotten this far yet can avoid to get into the same problem as I have now.

I made my Gravatar, the great app that makes your photo follow you everywhere on the web. When I made it I didn't know how it worked, but it was easy to set up and it did what it should, so I was happy. I connected it to my main e-mail and everything was fine.

Then I realized one thing. On our websites most of us have 2 users, admin, that we start with, and our name user that we add later (if you follow the training). My main e-mail was connected to admin, and the new e-mail I made for my site was connected to Marith.

So, what happened? When I respond to comments I always use Marith, and of course, it comes up with the "bubble man", because the gravatar shows up with the user admin, where my main e-mail is connected.

I thought, ahh this is easy, I just switch the e-mails between the two and everything is good. But no, I am not able to do that, because e-mail connected to the users are required, so if you remove the e-mail on admin, it won't let you go to the Marith, you can't leave the field empty, and it won't let you write in the one that are already in use on marith, because you can't use the same e-mail on both.....

So, what do I do?

While writing this, I was thinking, maybe I can leave a false e-mail on one while I fix the other and then go back and write in the right one....of, course, being new to this, I am always afraid of breaking my site, so I want to hear what you guys think about that last idea before I do anything that might be stupid.

And for you that still haven't added your gravatar, make sure you connect it to the right e-mail adress, good luck.
