Absolutely. Anything you want hosted, feel free to send it along to
andrew@nba-live.com or if you upload it to a free host first, you can use the
submission form and tick the "Host on NLSC" box and I'll download it and upload it to the NLSC; unfortunately we don't have a public upload facility at this time, but either of those methods will let me know about a new release so I can put it up on the site.
Probably easiest if you send along the .zip or .rar file to
andrew@nba-live.com along with any relevant details (basically what you'd put on the submission form if you were doing it that way) and I'll take care of it ASAP.
