Drupal 4.5.x or older

Discussion in a email_registration module support thread at http://drupal.org/node/186128 led me to further examine all the issues associated with using Drupal for a Facebook-like authentication system.

Facebook only uses Email addresses for authentication and full names for user representation. In Drupal core, using full names as usernames is not an option because there are people with the same name and usernames need to be unique.

Here's a list of issues I have run into making drupal compatible with this sort of user system WITHOUT ALTERING CORE:

Full Names are not in the core user object

The easiest way to solve this is using profile.module to create a fullname field or a firstname and lastname field. A users email address represents a definite unique identifier for a user. While a person might have many email addresses, no email addresses have many owners (that would sign up for an account)

UI Forms that select user need unique usernames

I´ve searched and searched but can´t figure out how users can put images in their blogs. Can someone please help me.

WYSIWYG modules depends on adding certain html tags to the filtered html list to get certain fuctions running, after being pissed off by this, i took a deep breath about and thought about, now i find the idea spectacular, it gives more control about the content of the input by users.
I began working on identifying tags that i needed. but this idea came to my mind, of making this post, it will be useful for future noobs, it is a good way for someone to check if he missed something, or allowed something hazardous, let's say.
