Thanks very much for the suggestion, but I fear that the work necessary to build a new website, or even to convert to gedcom (which I've never used) is beyond me for now. Perhaps I will change my mind in the future, but for now it's too daunting a task.
When I began my site more than twenty-five years ago, and ever since, each page was created and has been maintained using an old version of Microsoft Word, though in html format. (For at least twenty years, including now, I am using Word 2002.)
Most websites do not allow html pages created in Microsoft Word, apparently because of the formatting Word uses. Thus opening any new site would entail a painstaking re-formatting of every line of every page (after cleaning them up with Notepad, for example, all indentation and spacing are removed) as well as editing of many dozens of embedded links. Converting to gedcom would entail the same process.
