In general, I agree with sfgal--it's too much like enron.
If it's not secret, it would help to tell us what the company does, as that is an important part of evaluating a name (especially if you have other suggestions).
if you think that your website can overshadow enron's evil deeds, then go for "nron" but my suggestion wud be come up wit something more unique and original
you probably want to stay as far away from names that evoke negative reactions in people’s minds by association, you would never consider naming your company notzee would you?
