Here's a warning to all of you that still use MS Internet Explorer as a browser: IE flaw exposes weakness in Yahoo! filtering.
Lesson: if you must use MSIE, don't read your online email with it!
A better idea would be to switch to netscape or even better, FireFox, and use that for all of your browsing. I switched a few weeks ago, and haven't found anything that MSIE does better than FireFox.
