I just did a guest membership and there was not an option that I saw to enter a user name. I see that when I registered it appears to use me email address as my log in and user name.
I have enjoyed browsing the forum and picking up information from so many knowledgeable people, but a a little hesitant to post with such easily identifying information open to anyone that is lurking (as I have done for years).
The profile page will let me change my email, but looks like I am stuck with my email as my user name.
