CC-BY-SA is good with me. To be honest, I use either CC-BY-NC-SA or CC-BY-SA. The reason I use the non commercial one myself is because in Military, I used a few models by other people that were licensed under NC, thus, requiring me to use the same, and secondly, it's not meant to restrict people from using it commercially, its just so that they can ask for permission before they try to use it commercially. It's just nice to know.
But... are you using any of my stuff in here? Good god... I don't know... I should animate something... I think I'll volunteer for the bear.
Oh, and something else to ponder:
I'm going to add what's there to the tileset 'forest' in GAE trunk, that way the latest should always be available in a known location.
Will we still need to upload to this other site if we use the trunk? Oh, and if we do, I propose one shared account, similar to how we share the Glest Files account. Sure, its not security smart, but we only use it for a few things, and issue the password to trusted users only. The Glest Files account on filefront has never had any troubles... Plus, having all the files by the same "user" on their site will help keep them linked and prevent confusion.
