Keeping track of my new posts on this blog is pretty easy, and if you’re used to using an RSS reader, you can subscribe to this blog very easily.
For the wiki, if you click on “preferences” at the bottom, that will take you to a screen where you can change your password, but you can also choose to receive updates when changes are made (hourly, daily, weekly). When something changes, you’ll get an email, so I would probably choose the daily, if you want to get notifications.
I will be posting things as I get information (I just added to the Florence page some info about your flights, for example) so keep an eye on both of these sites.
