Still struggling with this. I've added it, as you say, to one of my 
__init__.py scripts - I tried this before and it didn't seem to work. I've 
even added

if not RegistrationTool.__ALLOWED_MEMBER_ID_PATTERN.match('a.b-_'):
    raise "oops"

To make sure it works, and that doesn't throw an exception - the product 
loads fine. However, 'a.b-_' is still rejected as a user id (as is 'a.b' 
for example). If I change the "isMemberIdAllowed" function in 
RegistrationTool to insert the following raise:

        if not self.__ALLOWED_MEMBER_ID_PATTERN.match( id ):
            raise "doh!"
            return 0

then when I try to join with a username as above, it throws the exception 
(I did this to make sure it wasn't being rejected elsewhere).

I've even tried creating a new CMF site (both plain and plone) to check 
that this wasn't a problem with the portal_registration instance not being 
updated along with the class, but this has no effect (I need to read up on 
th python object model here, I think).

And I've tried both restarting and stopping and starting zope between 
changes.

At the same time as the above fails, this gives the "ok" exception:

-----
from Products.CMFDefault.RegistrationTool import RegistrationTool

def test():
    if not RegistrationTool.__ALLOWED_MEMBER_ID_PATTERN.match('a.b-_'):
        raise "oops"
    raise "ok"
-----

while changing the "id" to include a space, or start with a digit, gives 
"oops".

I've run out of things to test and ideas for what might be going on. I 
*surely* must be missing something really simple. Either that or there's 
some odd caching going on somewhere?

Thanks for pointing that out - still learning python :-)
