That's not to say it's a "bad" website. I've never used it, but if you check it out and decide you want to you can set permissions for it to be allowed while not disabling the script warning for other sites
I didn't think it was "bad", I just felt uneasy about disabling any security. But I thought about it and went back and sent a note to their Help section looking for a workaround. I also thought about a temporary disablement for this occasion only. You see, it really is a nice looking webmail service.
While I was there I sent an email to myself at another address. It didn't work. I tried another, being very careful and that too didn't work. Then I saw a message at the top of the page. Seems they were having problems connecting to their server. Gulp.
But I'll try again tomorrow and my reply might be there too.
