I'm listing the ones that I had been using and know that they have safe tubes to use for PSP'ing. Pls. respect the wishes of some of the owners of these sites. Some of them want at least a link back to their sites (linkware). If they don't require linkbacks, of course leaving them a line or two in their guestbook is always nice.
If you know of any safe tubes site, pls. feel free to share it with the group. I will post more links as I get them from my favorites folder.
