This appears to be harder than I expected it would be. I'm doing a simple website for my daughter-in-law's PTA and they want a page for events that they can update themselves via an external text file. I've done this before in Flash and thought it would be possible in HTML but I've Googled and searched this site and haven't really found a way of doing it. Can anyone help out please?

Well, you can't do it with only HTML. HTML can't *do* anything, it's a mere markup language. But you can do it with a server side programming language as for example PHP or SSI that's available on most servers. There's nothing to it, but you must have a language that can do it available to you.

It's also possible with Ajax/javascript, but more tricky/less reliable than the server-side solutions.
