[FX.php List] posting an email address

[Bob Patin]

As with every web app that I see, I use the email address and a  
password for clients to login (unless my client insists on using  
usernames).

If the people who log into the system change their email address, then  
they will hopefully be smart enough to login using their old email  
address, and then change their email as it's stored in the system.

I would *never* use an email address, name, or company as the primary  
key; I have a client whose database was originally written that way,  
and it's been nothing but trouble for her, which is why she eventually  
found her way to me.

However, for logging in, I find that email addresses work well for  
usernames; I see the same method on most of the large sites I use on a  
regular basis, like Amazon.

The problem with using usernames instead of email addresses is that  
many people (myself included) might forget their usernames, but they  
won't forget their own email addresses.

I also write password-retrieval routines on all these web apps as  
well, so the users can retrieve their passwords if they forget them.
