Thank you, Scott. Once we have further comments from our RQTF colleagues, Janina or Josh will be in a position to decide whether to merge the changes.

There is also a decision to be taken regarding what, if any, enhancements to make to the conclusion section.

I've had a look at the work - your proposal makes sense to me and is a good addition.

Scott.

Thanks, Jason.

Afaik, this Cloud Flare work is the only content we need to incorporate in an FPWD publication. I'm proposing to try and get that done in time for consideration by RQTF at our next call on the 17th. Potentially, we could even resolve to ask APA to publish at that point.

Is that unreasonable? I'm not aware of other major work or industry changes re CAPTCHA since our 2019 Note. Thus, I think adding Cloud Flare to our note would constitute a worthy FPWD.
