Captain_nemo Ultimately, I suspect you are going to find difficulty garnering sympathy here. This is Flarum's official site, everyone here is interested in Flarum in some fashion and are using it because they like it over the alternatives. No, Flarum isn't perfect, no software is, but its design choices and technology appeal to a lot of people, enough to make them convert their own sites to use it. I'm not sure what you hope to gain by continuing to discuss your issues here, as they seem (and correct me if I'm wrong) relate less to Flarum's own UI design and more with Giffgaff's choice in a software move.
I suggest that you continue this discussion at Giffgaff's official site, or on more diverse discussion communities where you might receive a more balanced set of feedback. This line of commenting is starting to get off-topic.
