Any chance you have the sets of Charly aswel?
Oh and do you know if BriscoCountyJr is still active?
Also, I've seen you need to contribute with posts/uploads but unfortunately I haven't got any qualitative sets like you find on this site. If I can contribute in any other way, let me know. I'm happy to help.
The download links for the solo sets of Charly @ Beauty of Youth are replaced.
The other sets will follow in the next days.
Dear mods, is BriscoCountyJr around? Otherwise I would take care of these four Joya videos as well.
KilaLika, about your question: There are many ways to contribute. For example have a look into the replacement requests. If the original poster isn't available you can ask mods if you can jump in and answer the request. If you have sets of a particular model you can use search to find out whether they are already here. If not, you can create a new topic and post them.
