@mckinley@twtxt.net Very nice, thanks! :-) Well, at least the standard is pretty obvious in that regard. Although, I have to say, I prefer the “must NOT” over the “cannot” version. Interesting that they changed the wording in the draft version. Admitted, it’s basically a complete rewrite.

Now the only thing left for you is to file a bug report against Otter.
