I could put that on the web page, but that doesn't really help, because the problem is the people who can't be bothered to read the web page. I still get a fair amount of mail to my personal address rather than the PuTTY role address, simply because some people click on random links until they find an email address and then send mail to it, and these people are just as likely to see the link marked "Simon Tatham" first as they are to see the one marked "Feedback". They actually don't read the rest of the stuff they're scrolling past at all, as far as I can tell.

So my suspicion is that putting warnings about lack of phone support on the website would be useless at best, because those people who would be daft enough to need the warning would be precisely the people who would skip past it assuming it wasn't important. And it might even be counterproductive, since it might hint that there was a reasonably easy way to contact me by phone to someone who hadn't previously considered trying it...
