I've seen a couple posts regarding this topic, but none have been of any help to me, so I thought I'd ask. I'm trying to make a list of my users and some of their user information available to anyone who is logged into my site. Like their username and email, and the date they joined, things like that - all of which are included in the users table. However, as far as I know there is no way to search the users table. What would make this possible?

While I'm at it, there are a number of tables in my database that contain information that should be linked to the users table. For example, each record in a particular table contained the owner's Username and Email. Is there a way to make it so that when the users table is altered (say someone changes their email address) the corresponding data for the other table also changes?
