In a similar fashion to the wonderful service Zeno and others are currently providing, I'd like to throw my hat into the free host list.
I've had a VPS for quite some time that doesn't do anything more than run a demo version of my game; and I'm tired of letting the resources go to waste :) Currently it is running on minimal resources, but I am willing to scale upward as needed in the future depending on user load/usage.
Requirements are the same as Zeno's: member here for at least 1 week and 5 constructive posts or a single code upload of your own work.
Sweet, glad that you decided to do this. I'll be sure to sign up I've got a mud project in mind that I think most people will like as long as they appreciate the futuristic cyber punk style of things like Ghost in the shell or Armitage III kind of cyber punk.
