How can I upload a file in one of my usenet posts?
A. Though we won’t know how to do this in your newsreader, you should have a choice that allows you to attach a file on a post. The de facto standard on news posts is UUencoding. Though there are post that are MIME encoded also. Most good newsreaders will do this for you automatically, though some will need a helper applications to do it with. If you file is really big you should break it into smaller posts, but once again most good Newreaders take care of this for you.
