themed login pages extended fields no detail overwrites

— desired results —
– customed themed login, registration, lost password pages.
– extended fields.
– no system overwrites of user entered username and password.

using ‘register plus redux’ (free) to allow new user to enter own password and newsletter checkbox. works perfect for standard ‘wp-login’.

tested using ‘theme my login’ (free), ‘custom user registration’ (paid $12) & ‘insite login’ (free) to place login, register & lost password into themed pages.
process works, however the system overwrites the users entered username with eg. unverified_dhTf89E, when going through themed pages, but standard ‘wp-login’ process remains fine but looks to plain. not good.

– theme my login –
– set to /login
– themed pages with extended fields but overwrites custom username.
– allows standard wp-login pages

– custom user registration –
– system created pages
– themed pages with extended fields but overwrites custom username.
– allows standard wp-login pages

– insite login –
– set to /login
– themed pages with no extended fields from ‘redux’.

i’d love to hear any solutions u all might have.

thanks,
lance.
