Wow. I just realised. Nevertheless, I wouldn't term it racist.
I took the phonetic version of the Japanese word for link (rinku) and added an extra n - http://translate.google.com/#auto|ja|link.
I have to say that the thought of the name being racist never entered my head - I was just looking for a cool name and though rinnku looked good and would be easy to remember.
I apologize from the bottom of my heart for any pain I have caused.
