Requiring E-mail Addresses From Commenters
I've re-enabled the option to require valid e-mail addresses from commenters, so if you've already been approved as a commenter via TypeKey but haven't provided an e-mail address, you may be asked to enter one.
Why am I doing this? Honestly, it isn't to prevent comment spam (or to invite it for those ponying up e-mail addresses); rather, it's because I often like to respond personally to commenters, and it drives me nuts to write a long response only to find that I'm replying to myself.
Of course, if turning this option on makes things go horribly, horribly wrong, I'll probably turn it back off again. <sigh>
