Ok I click "unsuspect comment" I think I know why it did that, it's happened to me before. There have been replies/comments I've written that included a link and for some reason it would only go through correctly until I removed the link. But that hasn't happened in some time now. Maybe there's something wrong with your link here, but it showed up fine in my inbox. Weird.

Anyhow, I went to the link from my inbox, and I don't get the page you describe when I hit the Login button. It take me to another DW page asking for my DW account or create a new one. I don't see the options you describe anywhere.
