I recorded some video tutorials. I hope that these short videos will answer your questions.
The first video tutorial shows you what yEnc messages look like in your newsreader if your newsreader doesn’t natively support yEnc. This video will help you recognize yEnc messages so you know if you need a yEnc Decoder like yProxy.
The second video walks you through installing and configuring yProxy with your newsreader, but uses Windows Live Mail as the example newsreader.
The third video walks you through running yProxy for the first time and starting yProxy.
The fourth video demonstrates yProxy in action.
