The Great XUL/Neil Conspiracy.
There are a significant number of Neil's posting on the Mozilla XUL-related newsgroups. I think that there was even a thread once with three different Neils but no one else.
To clear up any confusion, I'm Neil Deakin, and my email address is either firstname.lastname@example.org.(which no longer works) or email@example.com. I wrote the XUL Tutorial.
There is also Neil Rashbrook who often posts messages that may contain traces of nuts. I am not him.
There is also a Neil Stansbury and, although not recently, a Neil Marshall, who also has a sympatico.ca email address. I am neither of them either.
In order to avoid this problem in the future, I suggest that any new Neils who may wish to post to the Mozilla newsgroups change their name to Stan.
