TypeKey Issues – Advice?

I go to this entry in wordherders and try to comment on George’s post. I see that I have to log in to typekey, so I do so. I enter my Typekey and it forwards me to a page that says:

Word Herders
Comment Submission Error
Your comment submission failed for the following reasons:

The validation failed.

Please correct the error in the form below, then press Post to post your comment.

It took my TypeKey, but seems to want my email address, even though I don’t have e-mail as a required component.

Wordherder settings are currently (toggled on):
– Do not accept comments from Unregistered Visitors.
– Accept Comments from Registered Visitors.
– Typekey Token entered properly.
– Automatically Approved Registered Vistors.

What’s going on?

UPDATE: I continued to the error page, as described above, re-entered my name, email, and URL (as per old 2.61 comment style) and hit enter. The comment went into moderation. So far, color me unimpressed.

I noted that according to their own documentation, TypeKey has issues w/ IE 6:

Caveats: If your weblog domain is different from the domain of your Movable Type application, commenters using Internet Explorer 6 may have trouble logging in to comment on your site. This is because Internet Explorer 6 doesn’t allow your weblog to fetch your cookie information from Movable Type, which contains the logic to decode it. For example, this situation would arise if your weblog was at www.joesjournal.com but you log into Movable Type at http://www.my-hosting-company.com/cgi-bin/mt/mt.cgi

I’m concerned that this might be a problem w/ the wordherders, since we are all on subdomains. Anyone else having these problems?

Meanwhile, when I go to make sure that my comment did in fact go to moderation, I have 5 new nasty-spam comments waiting to be moderated. If I have Typekey only, with no registered users, and they are (according to blacklist when I despam) already on the blacklist, how the heck is the spam getting through?
