databases vs tables

[david sobey]

hi

just a few questions:
1. apparently MySQLAdmin is used to create, delete databases, stuff
like that. But this can all be done through MySQL, ie just the normal
MySQL -u user -p etc etc. So what's the point of it?

2. I'm creating a website with a basic discussion forum. I'll also
have a member sign up and login system. The website, however, will
ultimately be used for discussion forums, project lists, membership
info etc for a club. Should i store the member info such as login and
password, age etc in a new table or new database. What are the general
rules regarding when to create a new table vs database. If i use a new
table, how do i create some organisation to seperate discussion posts
from project posts or news posts, other than using unique table names
like "DiscussionPosts" and "ProjectPosts". Ie how do i create some
sorta heirachy maybe?

3. To access the database to post discussion topics etc, users should
have a login and password. Should each user have their own entry in
MySQL.user database table or should i just create an Admin and
LimitedUser account in the MySQL.user database?

cheers
