    Summer Greetings!

    I would love to continue receiving your blog, and would like to update my email address to
    “Don Ostrow” .

    I tried to go to WordPress to create an account to receive your dy/dan blog. The up front info says the first year is free and then it renews at $18/year. When I went to sign up it said that the first year is free, but it renews at $48/year. As a retired elementary math specialist, I am willing to afford the former prices but not the latter. Please advise.

    Love your stuff – have been a fan and a user for years. Thanks for your great work!
    –Don
