I have been a long time Yahoo! Mail user (since 2001), and a paying customer of Yahoo! Mail Plus for 5 years+ (since 2003). There were no Gmail back then, and I needed a permanent email with POP3 access. Yahoo! slowly improved their services, although one thing that I have always been annoyed about is the unavoidable error that will be displayed if I try to access the web interface while my email client is pulling email via POP3. Every time!
In June 2004, I received an email informing some improvements. I didn’t really noticed them, really.
But then again, this is what I am really disappointed about. The “temporary” message has been there since the release of the new GUI.
And here is the antique filter form. Furthermore, Plus users can only create 50 filters. What’s that about?
Come on, Yahoo! please improve Mail. While you’re at it, IMAP service wouldn’t hurt too.
