Search the whole website for new features, screencasts, faq, known issues
Watch screencasts, they are now grouped by category and can be found in one place. I plan to add more short screencasts before the release of 2.0.
Enjoy the brand new blog. Much improved categories, commenting, and archives.
Check for known issues. The same information is displayed in the "Mailplane->Help->Support Feedback" window.
Subscribe the FAQ, blog, known issues, and screencasts.
I hope you enjoy the new design and improvements as much as I do. If anything isn't working as it should, either leave a comment or use the new contact form to get in touch.
