Table User

[gengar003]

Okay, i'm not very good at mySQL, which Is why I'm asking this:

First off, what do all the Tinyint, null, etc things mean?

Second, Let's say I wanted to add a field to the table User, containing an on or off value, how would I do that?

And, once that was done, how would I use php to check if it's "on" or "off", and to change it to "on" or "off"?
