It's a lot more then that yes
Oh and you got my name right NE
Well coding something like what you're suggesting would be a lot of work.
However at Lostheaven we have quite a system to handle downloads.
It's combined with phpBB, and it would fit most needs, but I didn't code it so I have to ask the guy who made it if I can use it here.
Since he made an entire CMS around it, it might even be fit for a site like this one.
Also a lot of extra coding will probably still be required.
I'm not sure if I have enough time to start on something like this but I'll consider it
Here's our download system ->

Who is your main coder btw?
