For anyone reading this, the plugin author wrote me directly: WP has apparently closed the plugin for reasons of title and keyword formatting, nothing related to the functionality or security of the plugin itself. Warp iMargick will apparently be released on another site shortly; it is being actively maintained, as of this date.
Okey-dokey. Since you have no other way to reach you AND you haven’t even acknowledged my message in 5 weeks, I’ll delete the plugin and review your support instead.
