Listening to a piece on Newstalk about the barrier-free M50 tolling, I decided to lookup http://nra.ie. However, as with a lot of sites still (in this day in age, yada yada), that address doesn’t work, and you need to use www.nra.ie.
However, if you visit the former, you’ll be prompted for a username/password for bfcnet.into.ie. www.into.ie is the website of the INTO (Irish National Teachers Organisation).
Sites not working unless you use the www. are annoying enough, but sites that use the root domain (nra.ie in this case) to point to a non-public website, or a website of a different meaning altogether are far more annoying.
