Even though the site isn’t finished, a number of people have recently signed in and created new accounts. In particular, there’s been a noticeable uptick since the beginning of the year. Many have even started charting.

Thanks for the vote of confidence!

Since the site is still not feature complete, I’ve bumped the end date of the free preview period back to March 31, 2010.

The minimal set of features I’m envisioning includes:

  • Plotting baseline temperatures
  • Printable charts (PDF)
  • Optional sharing online with instructors

Until then, please continue to enjoy the free preview!
