You are most definitly thinking of a different site than what I am speaking of. They had a beigeish background with light yellow background on toolbars and stuff... Google might have a cache of it, but I am not certain.

A few of the former HDC members and 1 or 2 of the admins started a new BBS that I just found out about, it's http://hackersbbs.com Seems about the same as the original, but not near as many users or activity.
