The recent launch of New Vegas and the gold rush style race there's been to get a lot of the great mods from Fallout 3 converted over to New Vegas has raised the growing concern the staff have had recently regarding the use and/or redistribution of other author's work by members of this community and how difficult it is to ascertain a mod author's wishes.
Before I go on I'd like to remind everyone that converting other author's work from Fallout 3 to New Vegas is strictly forbidden right now unless the author has specifically given permission for you to do it.
All the staff at the Nexus are extremely pro modders rights. That means if you make something from scratch, such as textures, meshes, animations or scripts then these belong to you and you can do whatever you want with them. It means you get to choose how, where and when your files get distributed. It also means that other users don't have the right to do whatever they want with your assets unless you specifically say so.
Many mod authors give specifics about what permission they give to everyone in regards to modifying their work or redistributing it in their mod description or ReadMe but a lot don't and then get upset when others "steal" their work and use it in their own mods.
The changes implemented today are a step towards trying to rectify this issue by asking file owners to specifically state how they would like their file assets to be used and redistributed. It also gives plenty of room for mod authors to explain things in much more detail. These changes will greatly help everyone to better understand the permission issues on the site and will make staff actions against thieves much easier and much quicker to action.
You can find the new "Distribution permission" settings when adding a new file or by editing any of your already uploaded files by going to "Manage files" then "Edit attributes".
There are also pink warning boxes galore informing new authors of the most regular pitfalls and a new tickbox you have to agree to before you can upload new files to the site insuring the files you upload belong to you or that you have permission to upload them. There are no excuses now people.
