okay, at risk of making a mistake about it i'll try and be the first to fill you in on what happened...
basically, from what i know, skinz.org was owned by a business called "eFront" who had a large list of different sites that they used to promote merchandise and whatever (is that right?), so anyhow, about 6 months ago(?) they started to run into financial trouble and then they stopped paying the admins of skinz.org and other sites on their list. There were some odd shinanigans happening with 2 of the main CEO's of the company and their entire chat logs were released onto the internet by a disgruntled employer, exposing the hypocricy of eFront and how they treated the many different sites as a money laundering scam ...
anyhow, skinz.org didn't last long after all that becuase the skinning community have 'moved on' ... some1 at eFront was acting as the admin cuase all the other great people like shoggot, and the thirty4 interactive people had since left due to never being paid ... No-one is really administering the site and it's now just a stagnant place without a community basis.
- that's my interpretation of what happened and how things are - i'm sure some1 around here will be able to add a more enlightening spin on it though -
