I've given up. I had to turn off all the updates because my home/office email was deluged by messages every day so now I will only check Activity every 2-3 days. While I actually am tech savvy and use different kinds of media all the time in the classroom, I find this site to be unusable, taking far too much of time I don't have to even try to post a message. (It kept telling me I couldn't post where I wanted.) Moreover, it seems to have only a marginal relationship to travel anymore. So compared to the famous April update of a couple of years ago, I think this site is much worse and I'm not interested in it except for the people I got to meet on the old web site.
For those who like it enjoy! I'm not trying to be difficult and certainly not Luddite.
