To upload flash you're going to need a good file hosting site.
I use
DrivewayOnce you have a good storage site, all you need to do is upload your flash files (to the storage site), then send us the download links.
A good way to send the links in a post is by using BBCode.
The one for linking it is, [url =http://somewhere.com]Text Goes Here[/url]
(minus the space between the url and the = sign.)
Post any questions and comments here.
