I think the website needs to be more active, I suggest you guys recruit some more MODS and make some competitions like who posts a number of threads will be the winner or whatever.
This will help a little bit.
There should be also a seperate review section for NZB indexer and DDL sites as KKT has this feature and people have for example a better imagination how some nzb indexer or ddl boards they are trading/buying look like!
