The SF K Files has a new feature that allows you to receive email alerts for new forum topics as soon as they are posted.
Simply go the the SF K Files Community site, here, and then visit the "Account Settings" section in the upper-right hand corner. Check the box for "Notify me whenever someone adds a new forum topic." Now the Community site will feel more like a mailing list a la Yahoo Groups.
And remember you can start a forum topic any time here. This is also a great place to post school events and links to interesting articles on education topics.
