Now i'm not very educated in the history or underground areas of this forum. But, adding some more non-underground game forums would be a good investment; for instance more ijji games, currently the only sub-forum is Gunz... that could be extended to an ijji section. From past experience their security isn't that hard to get through ( i admit i haven't checked for about 2 months.)
In conclusion, this would bring more people to the forums. The extra games would bring in google searches; and with extra people, there is more of a chance for experienced hackers to contribute.
