Your welcome. Actually, its pretty simple. Here's what you do. You can click on anyones username. For example, click on your username from the above post. It will take you to another screen that has a box on the left hand side that looks similar to a calender. Now, click on the letter "A". What that will do is pull up all usernames that start with the letter "A".

I noticed in your original name that you were pretty sure your user name started with Guinness. So, I clicked on the "G" and looked for any usernames starting with Guinness. once I came across Guinness97, I look at the name and noticed it said Mark, same as the name you created your new one under. So... there you have it!

Glad I could help!!!
