At least they are not stolen models. :)
Anyhow, surely can use some work, but what exactly do you mean with making it work?
What do you want to make of it and what do you want it to do.
As for uploading files, use
mediafire, it is a free online file hosting service and many people use it to share files and add-ons. :)
Make an account and you are ready to upload your files there.
Then get the link and post it like this:
[url=linkhere]text[/url]
Replace the text with like the name or something.
Alternatively you can post the link like this:
[url]linkhere[/url]
But the first way is cooler since you can link with a word instead a long link.
Alternatively if you have like only like 1 file that is not too big you can use the attachment feature of the forums:
Open the additional Options menu before pressing post.
Then select your file you want to share at the attach part and post it away. :)
