Is there a section in this forum that would be appropriate to ask for a reseed request (in addition to the reseed request button already available on a torrent's page)?
also is there anyway to double check if the request button actually worked?
Not really, and yes.
1) The reseed request button sends a private message to active members who have indeed downloaded the torrent--I get that sort of message at least once per week. Not everyone uses the forum, so a posting here might not get seen by someone who has that material. It's remotely possible that someone reading the forum might have the requested material from some other source and be able to start a new torrent with it, but that's a longshot. While you could make a "request" posting in the Forum, I think your best bet is to use the reseed button.
2) After clicking the "reseed request" button, the system will say something like, "Success--14 PM's sent." That way you know it worked--meaning that people who have downloaded the torrent have been sent a reseed request message. I think most people read their messages, but some people are not adept at reseeding torrents, and others might have deleted the material and thus not be able to reseed it.
If, after hitting the button, the system says something like "No PM's sent," it means that nobody who downloaded that torrent is still active on the site. That's happened to me a few times, and it basically means that the material I want has died and gone to Porn Heaven.
