Microsoft MSN Butterfly beta testers will shortly start testing the next revision of the MSN Explorer software. There will be minor changes and the addition of features like PhotoMail. PhotoMail allows you to embed images into your email and annotate them, apply effects to them etc just like you would in Microsoft Word.
MSN Beta testers will be receiving the MSN Explorer Beta CD shortly and it"s expected that the beta will run until January.
Update: This quick beta will be to test increased quota sizes for MSN Mail. It"s mainly an engineering patch and will remain at MSN Explorer 9.10. The beta is due to run for a few weeks only.
