[Typo3] fe_user Newsletter field

[andreas stein]

Dear List,

The whole night i'd puzzled around with no result. Really hope you have a
hint:

I use the extension direct_mail (1.0.8) which extends the fe_user and the
tt_address table with the fields 'module_sys_dmail_category' and
'module_sys_dmail_html'.

This should be filled in by the extended fe_user  form. BUT NO WAY- IT WILL
NOT work.
I tried it also by extending the fe_user table with OWN 'string' FIELD
(tx_test_testfield). Everything works fine - fields are shown in register
form, also shown on the aproval page, but they are NOT STORED in the
DATABASE! Why??

I tried it as well with the sr_feuser_register. Its the same: Fields are
shown in the form and on the aproval page, but they are not stored in the
database.

look forward to lift my curtain in front of my eyes.
