You may have noticed that I'm trying to tighten things up a little bit. With regard to that, I might be forced to disallow email-addresses that are well-known to be acquired easily, ie
xyz@hotmail.com. If you have registered previously with a hotmail.com or similiar account, it may be a wise decision to change this addy to a more reliable different one.
To be precise: I am not asking you to change your
xyz@hotmail.com email address right now.
All I'm saying is that I might have do that in the near future. This is just a message to inform you so that don't get locked out by accident.
And yes, the email address entered in your profile is protected against spam.
