Comet Cache is NOT caching this page, because the current page contains `_wpnonce`

<!-- Comet Cache is NOT caching this page, because the current page contains '_wpnonce' or 'akismet_comment_nonce'. Your current configuration states that pages with dynamic '*nonce*' values in the markup should not be cached. See http://wsharks.com/1O1Kudy for further details. -->

I get this on every page, does that mean I cannot use cometcache on my site?
Thanks.

If you are using Pro, go to Logged-In Users and set Cache Pages Containing Nonce Values in Markup? to Yes.
