The link to the user guide (when launched from marketxls inside Excel) throws a 404 (not found). This page is called: http://marketxls.com/knowledge-base/whats-new/ It's also the same as 'What's New' which also 404s. You need some redirects here. I don't know if there is a full manual somewhere, but at least a few links would be useful, e.g. to the Knowledgebase: http://marketxls.com/knowledgebase/ A stub page with some pointers is better than an error. I saw a spreadsheet previously with a list of functions, I can't find this now, that would be another candidate for this page.
