Hello ,
Well, my experience is on my age, I can contribute uploading and helping somewhere in the forum, as I do in my other trackers.
For me, community is a big part of what makes that tracker worthwhile. People tend to think of 'community' as people hanging out in irc/forums/shoutbox and chatting, but it's so much more than that. It's that feeling of community that keeps files seeding when you really don't need to, that drives people to use their ratio to help others with similar interests when they get into trouble, that leads people to find copies of files on other sites to fill requests when there's no reward to be 'won', to search their discs and drives for that thing they downloaded a few years ago because someone else is interested in a copy, to help someone out with some random technical issue that's not even torrent-related, that leads them to give over money in exchange for a little star next to their name and leads them to give up a hugeamount of personal time in order to help a site out. For all those reasons, 'community' plays a huge rule in how well trackers function.
Thanks you.
