I want to create a user login system for my website. I've implemented the Login block, and activated user access at the Users and Groups page on my dashboard.

First of all, if I want my users to be members of my site, instead of my Concrete5 site, should I create a MySQL database and the login system the regular way, or should I just stick with Concrete5's login system with the Login Block? If I keep it the way it is, using the Concrete5 system, then are those users members of my site, or Concrete5?

Also, I'd like to display information about the currently logged in user at all times. I am aware of the user info at the bottom of the page, but I'd like to add a bar to the header. Something like this:


-------------------------------------
| FRANK THE TANK |
| You are currently logged in |
| |
| My profile Sign out |
-------------------------------------

"My profile" and "Sign out" are links, of course. How do I do that?


Thanks!
