unable to toggle nsfw in default front end in some communities

In at least tickling and shinyyiff there is no easy way to toggle or set nsfw using the default web interface. The checkbox either doesn't load, or disappears immediately. For creating the post, nsfw=true can be manually added as a variable. I'd have to dig into the api to see if there is an easy way to toggle a post that has already been created. I don't know if this issue is a problem on apps or other front ends.
