email user validation, captcha

[Thomas Arthur Oehser]

I must be looking in the wrong places, I'm having trouble setting up
either email validation as I would expect it to work, or captcha, and
I'm not sure where the documentation is for it...

In the 'preferences' tabs (I'm running the svn tips 1674 + b1.5 xar),
I have email host and admin email address- which I have sending the
email- but, after it sends the confirmation email, the user seems to be
actually registered, it isn't waiting for a response, for that matter,
there doesn't seem to exist the configurations I would expect of a
mechanism for it _to_ listen for a response.  Does this mean that I'm
supposed to manually set the rights to require a group membership,
then manually look for responses?  Or create a script that listens
for email responses and adds users to the "verified" group?  I'm missing
major chunks of how to get it to work.

Also, I have not found the option or tab or preference (or
documentation) for the 'captcha' functionality.  Probably I just need to
be pointed in the right direction?

Desired functionality:

- Registration first requires passing a captcha test.
- The user enters their email address.
- Their verification email is sent, with some kind of GUID.
- Their ID is created in some 'locked- waiting for confirm' limbo.
- XWiki receives their email and confirms that it has the GUID.
- Their status is changed from 'locked' to 'normal registered user'.

 o What parts of this are currently implemented?
 o What parts of this are wishful thinking?
 o Where can I find documentation and help?

-Thanks,

-Tom
