Yahoo is asking for new ideas. This would be a win-win for all concerned: You'd be doing EVERY poster who frequents Yahoo's discussion boards a tremendous favor by initiating a feature most other forums have utilized for years: an email notice, whenever a thread you are posting on receives an additional comment. It isn't as though Yahoo lacks the funds to pull this off..so, I'd be most interested in your reason for omitting this option when so many smaller, less funded forums make it standard practice. It would increase your volume..unless you're against that as well.
Don't waste your time with Yahoo. They just don't care. It took them over two weeks and several email requests before they discovered my real time quotes were shut off on their end. And I'm paying for this service!!!
I've asked Yahoo to repair their "Filter Headlines" option, which stopped working some time ago. This feature was very useful for filtering out much of the "junk" news that Yahoo lists for each stock, and made perusing the news for my stocks much less tedious.
I urge other users to make this same request to Yahoo Finance.
