Sorry, but I don't understand.
What on earth has your ISP got to do with it?
Can't you use a newsgroup independent of your ISP?
I connect to these newsgroups with the server: msnews.microsoft.com
That is not dependent on my ISP.
Why can't you?
I have no idea why you can't bookmark the site, but if that is an IE7
problem, then ask there. I fail to see why you cannot save a shortcut
to a site you have been supplied. Copy and paste it somewhere you can
find it or just recall it in IE after you get there from History,
AutoComplete or TypedUrls.
