I'm not fixing anything. There's tons of links to my site, and now they're all dead. Mameworld seems hell bent on migrating to .info which means (as far as I know) all of the links to my site are now defunct.
Watch for a new development soon, with what I hope will be a better, more permanent solution. 
It was a good run with mameworld, and the guys were really great, but every year the registration would lapse because honestly I think the guys who started it have very little to do with it any more.
Stay tuned!
The original guys do indeed still control it.
Hell bent on a move to .info? We had no choice, ztnet are the guys who have control of the domain, we do not have the login details, they are the guys who let us down, and they are uncontactable completely, so we HAD to move.
The main webpage is now at www.mameworld.info.
I have manged to get mameworld.net temporarily redirected to .info and am going through a change of ownership battle to gain our domain from ztnet.
Twisty emailed you all the details, but your email account has him blocked out.
Hey Roc!
You must admit, your interest (and especially KC!) in mameworld has likely gone way down over the years. Well or at least your participation. I mean it went from almost hourly updates on the main page to maybe a couple a month, and twisty seems to run the place (just my perception). Don't get me wrong, mameworld has been up longer than the arcade heyday lasted, and it's normal to lose interest over time, in anything.
I might also have been a bit harsh in my wording "hell bent". I know it's ztnet, but you must admit it was a yearly occurrence (not nearly as bad as this year), and you really should have somehow gotten is figured out by now. Jeez, when i re-read that last bit, it sounds harsh... not really intended that way, after all it's all just a hobby.

So the auto-redirect from the old .net links to new .info may just be temporary? :sigh: I guess I'd better go back to manually fixing links. And yes, I know it's not your fault!

At the very least, it's good to know you're still alive and kicking.
