But no one answered. At last I found this list of PR submission sites.

Added 3 more.

Sorry, I just saw this post. I have a site that has lists of search engines and it includes other things like press release sites.

I pulled my list and then removed any that have already been posted. Some of them charge fees to distribute PRs. Most should be active, but I don't check them very often and some sites may be gone. If so I apologize!!!
