Since there are no stupid questions here, I have a NOT stupid question about 
these descriptions of an interesting and interactive site:
-displaying forms with user-interactive features: What does this mean? Me 
thinks this is more than just an "email me" button...

-gathering and validating user input: Does this mean just finding out stats 
about who visits your page?

-turning a simple web page into a full-blown web application: Please explain 
what a full-blown web application IS....(and why is this preferable to a 
simple web page?)

-mouse interaction w/ events: Ummmmm... mouseovers?

-animation: I do know what this one is!

I realize I have asked a lot of rather simple questions. I find I'm often 
totally confuzled about some (most?) of the subjects that fly on this list so 
I'm just sucking it up, asking and hoping I'm not the only one who silently 
ponders these things.......

Sherill, who wants to play too.
