Ok, so I don’t use Messenger that much, but I just tried to log on and it refused my details. I noticed that the new messenger password box only allows a limit of 16 characters and my details were longer. I use Technet quite a bit so tried logging in there with the details and same thing, limited to 16 characters !!!!! I had to go through the process of changing my password to get in. 16 characters may seem a lot but for those of us who are now in the habit of using pass phrases rather than passwords it really limits what you can use.
Ok, so this isn’t really a rant but it annoys me that some WEB sites limit the range and/or length of characters you can use for logging in and I never expected this from Microsoft.
