[Zope-CMF] using email address as userid

[Joseph Bella]

Hi all,

I'm trying to create a site where the user logs in
with their email address. CMF seems to have a check to
make sure we dont add any users with nasty things like
'@' and '.'  Is there a good reason for this? (ie Will
I break something if I tell it to go ahead and create
the user anyway) 

If the best solution is not to store the email as the
userid, does anyone have any tips on what I should use
instead (a numerical sequence?).

Thanks in advance...

joe
