Forum File security question
 

Hi,

I have a question, which I can't find an answer to in Google or here.
We have an car forum, and I have manuals in PDF format.
Now I want to place that pdf files on my server, and give access to the files.
That isn't to hard.. But I want that only the logged in users have rights to download the file.

If users aren't logged in, they may not access the file.
Is there some fix/idea for the issue?

Thanks in advance!
