The m6 boards suffered from poor maintenance on the provider's part, IIRC, and basically crashed horribly at one point, leading to the mass exodus to Tex's OF where we all are now.
At the time, I was a moderator on the m6 boards, and for a long while Martins kept it up for reference only, no posting. I never lost my mod privileges, so I could hunt around in it pretty easily, but at some point it just seemed to stop working all together, maybe Martins just quit paying the fee or something.
Meanwhile, the initial move to OF had some hiccups, as somebody got here before some of us and registered with other people's usernames to start whining about things and stir up trouble. At the time of the Great m6-o-clysm, m6 was having a lot of problems with trolls and so forth, but Tex managed to lock things down here pretty quick.
ar81 was, well, shall we say, kind of a volatile personality, and so were some of the others on my list.
I do wonder about Art sometimes, I think he actually bought the rights to Star Frontiers from TRW when that company collapsed or something. I used to play that RPG growing up and me and my brother still have the box sets and a few pewter miniatures.
