Bruce, I didn't think, from what you said, that there is likely to be anything offensive. I don't really understand how the Research Machines filter thing works. It's not nearly good enough at what it is supposed to do - ads get on the screen from innocent looking sites, very strange addresses show up in searches and so on - I wouldn't really want the children hanging round here, though its unlikely, and at the moment, we don't use the net enough, and it's enough under control not to be a problem. I suspect that it's one of the more technical objections, like the one which keeps me out of the chat. The alternative is that someone did take offense and reported your site as a problem, but that doesn't seem likely. Or maybe it spotted the letter string ero, and thought it meant something else. What is really irritating is that I don't have a teacher option of switching off the filter, because it is at the service provider's end. Given that there are grey areas, that would be polite to a professional.Penny
