How do I upload a park?

I tried to upload my park but it said that a nl2park file does not work. What do I do?

Save it as a NL2package.

i suggest to the mods/dev of this site to make a upload guide at the exchange/upload-park page.

thanks

I know this post is a little old, but I still have a little question. (: How do you create an NL2 package? I've never uploaded a coaster. Thanks for your answers! (:

In the editor, click on "File" in the top left, and then click on "Save Package..."

It's worked out! Thank you very very much for your help!! :D
