 Hi. Thanks for that explanation. I'm not a topic expert, just an interested copyeditor, so I've moved your comment to Talk:Espalier for the benefit of the regular editors. 

 Regarding your difficulties creating an account: if you'd still like to create one, there are various options depending on what problem you're encountering. One option is to send a brief request to the email address given at the very bottom here. (that will arrive at our OTRS system, where an experienced volunteer should be able to assist you). Also, there's a video demonstration of the signup process at Help:Logging in, in case that solves your problem. (all that is required is a username and password). However creating an account is not at all necessary. 

 Hope that helps.
