I agree with sukebe . I guess, we really need to create a reward system to motivate the members to contribute.
I am very unmotivated to post more torrents in here. I already explained it in here 
link
Why we post torrents in here ? very few people keep seeding and very few peolpe say thank you.
this torrent REALLY MAKE ME PISSED OFF: 
link 
very BIG torrent. I stopped all my others downloads tasks because A LOT of people are downloading it. more than 30 peers completed the download at same time. 30 seeders I created.  3 hour after it, is now ONLY ME SEEDING IT ! all others seeder stopped seed !
This make me pissed off and I deleted the game from my HDD !
and 
NO ONE SAY "THANK YOU" TO ME !
If at least the people thanked, I would not care, but the people not care in thanking.
I have a VERY SLOW upload speed. I suffer a lot seeding something alone.
But, no one care. No one say "thank you".
All others foruns have some kind of "reward system" , like a reputation points or a RANK system more complex ( common in ALL chinese foruns) like this:

The partner drop most loves  
Condition on-line 
OR A 
THANKS SYSTEM, like P2pzone 
link
you click in the button: 
and is added a "thank you" points in the thread and in the "RANK" of the member 
when, everytime we can click in the small "heart" button inside of the thread, show a list of the NAMES of the members that clicked in the "THANK YOU" button of this thread.
A thread with a LOT of "THANK YOU" points means that this torrent is very good.
I really 
LOVE the  THANKS SYSTEM of P2pzone . is really THE BEST award system of the world. these "thanks" points increase the RANK of a member.
exist members that have more than 5.000 "thanks points"  	
mg:
it is impossible for shibuyabashi Forum to grow without a RANK system or a REWARS system like the "thank you" system. .
All the other forums use a system like this. we needed to use also.
I really NOT like the REP Points system too. The "THANK YOU" system is better.
We 
NEED a REWARD system or a RANK system, chompy.
