For those having trouble leaving comments:

Evidently Google's new settings have caused headaches for blogs everywhere, and I'm sorry it's been so inconvenient for some of you trying to post homework assignments. Follow the steps below (the first one should take care of the problem).

You may have a problem with authentication, and with cookie filtering.

First, try a different login procedure.
1. Login to Blogger using "www.blogger.com".
2. Do not check "Remember me" or "stay signed in".


If that does not help, try a second time..
1. Clear cache, cookies, and sessions (not just cache or cookies) - then restart the browser.
2. Login to Blogger using "www.blogger.com".
3. Do not check "Remember me".


Alternatively, stop filtering "third party cookies", in your browser and on your computer.
