Is manager user profile form same one as websign up form ?

Is the websignup form in the manager (the one you see when clicking on a user) the same one being used on the front end or are they indepenant from one another ?

the reason I ask is I would like to try and customize the websign up form and have it match in the manager user profile as well

how would I go about doing this

revised update:

man am I close to cracking this riddle, I managed to create one extra field in the frontend websignup form and also matching what is in the manager webuser profile

is this right ? I had to add the extra field to all these files

mutate_user.dynamic.action.php
mutate_web_user.dynamic.action.php
save_user.processor.php
save_web_user.processor.php
websignup.inc.php
english.inc.php

geez man that’s a lot of files to have to add extra fields too he he but i’m stil not able to save the info in the webuser profile it says error in student attributes, not sure if i’m missing something.  It also doesn’t add the info when a webuser registers
