Some staff and volunteers pick it up quite easily, if they haven't already seen or used it before, but several people just don't do it, and instead I get a phone call or email saying "can you put this on the website?".
Incidentally, do you find a lot of people simply can't be arsed? One of our presenters (we're a radio station) is tech-savvy, has an iPhone, a Macbook, uses Facebook daily and so on. She's also one of the worst offenders for emailing me stuff to put on the website. I wonder if some people just plead ignorance to avoid having to do it themselves...
Anyway, back to the topic at hand, it would be one less excuse if we went to a solution like this - where it's simply a case of navigating to the page, clicking a button and editing it.
