You mentioned that I can ask to see your solutions and I interpreted it as wanting to help me fix it for me. All in all, I am mostly used to how websites have worked since forever – you click a link and it either opens it in the same window/tab or a new one. You go back/close it and you’re back where you last clicked the button. It’s not so simple with TW since it opens all the tiddlers on the same page.
Just a note that traffic signs are no universal language – they can ever so slightly differ between countries and usually are most well understood by active drivers. Which isn’t necessarily bad, I don’t know the target audience of the wiki in question.
