If it won't let you sign up for an account (I assume thats how you submit a site), you could always email Nicholas Thompson about it, seeing as this looks like his version of it.
I should imagine it has run out of steam, this wasn't the first webring attempt

Oh, and I recieved the web form you sent, I do agree that both my games are pretty - maybe too - hard, and I think that the problem stems from my inability (as the creator) to judge how hard the game is for a range of other people - I always make the assumption that someone out there will be better than me at it, lol. A friend thought that Minestorm was alright difficulty wise on Easy mode, but yeah, very hard was ridiculous now I think about it

While those games are a couple of years old, maybe I could tinker with Minestorm to make it easier. Speedball would probably be more time consuming to change as I think the annoying difficulty was mainly with the way the levels were designed.
edit: I probably could have emailed that to you, but I seized my opportunity so oh well
