Excerpts from the news article: Leaked information from Yahoo reveals that it would be partnering with the world's leading SEO forum Blackhatworld and offer Unlimited PM storage for its users. This is proposed to be integrated with the upcoming forum upgrade. Aside from sending and receiving PM, users will also be able to send and receive emails through the PM section, with 50MB attachments and unlimited message storage, along with cloud storage for pdfs and jpgs etc. This system is said to have been under testing for the last 6 months or so, and once implemented all users of the foum would be able to send and receive unlimited Private Messages as well as emails. It is also proposed that the 1 PM per 63 seconds limitation would be lifted too since its going to be Yahoo's responsibility to limit Spam and automated messages here on. This is expected to go live in a few week's time.
