Yes, absolutely. After you log in, you can take credit for a balloon once the flight is complete. On the balloons that you launched, you will see a 'claim' button to the right-hand side. Your name will appear as the author, and others will now be able to see your name linked with that balloon or comment.
If you don't yet have a registered Balloon account, you'll need to create one in order to claim your balloons. You can claim your account using the orange button in top right of the results page.
Claiming a balloon or comment does not change the anonymity for any of your other balloons or comments.
