ENWorld blog entries are still preferable - after all, they bring more attention to the blog entry, and thus to the Arcana Wiki - but ultimately the inability to register there shouldn't stop people from submitting.

Apparently, they now ask d20 rules questions to register…

Really? Now that is crazy!

Anyway, he submitted his contribution via email, and I'm going to let that count.

On the other hand, if somebody simply can't register on ENWorld, I agree that another option would be nice… although the only two things I can immediately think of that would actually prevent somebody from registering an ENWorld account are:

1) A lack of Internet access.
2) A previously banned IP address or account.

If the former, such an individual would also be prevented from participating in the contest, so taking steps to accommodate them seems like wasted effort. If the latter, as callous as this may seem, the inability to participate in an ENWorld contest seems like a fair penalty for anybody who abused their ENWorld account to such an extent that it to warranted the banning of their IP address or account (it does take either a lot of bad behavior or grossly inappropriate behavior to get banned from ENWorld). I hate the phrase 'tough luck' but I think that it applies here.

If you missed your chance (though a link to the contest has been given on the main page), don't fret - I'll announce the next contest tomorrow.
