best forum site (maybe a few) catering to torrent requests

Hey what's the best forum site (maybe a few) that caters to people's TORRENT REQUESTS?

I have a list of "not so easy to find" torrents, and I'd like to ask people's help in either tracking them down or in uploading.

I use the following TORRENT SITES (for both finding torrents and asking forum questions). Which other LARGE TORRENT SITES do you use for both finding torrents and making requests?

Note: Please only share the sites with the biggest number of users (and therefore, the most amount of torrents).

Thanks in advance....
