Check out the news in the last week on the main JK2.net page, and you'll see that the file server has been having problems. So your file most likely won't be posted until that's fixed.
Now note that I'm not the one who handles files (Andy would be the one to talk to), and my JK2.net addy is broken (it hopefully will be fixed someday), so I can't post it even if I wanted to.
Just be patient I guess, and if you're desperate, send it to some other sites. We'd love to post your file and I'm sure it's worthy, and it's nothing personal against you.
Don't let this discourage you from sending us stuff in the future, but there's not a lot that we can do right now. Hope you understand....
