You know, there are already a bunch of other Lemmings sites. They can give you info.
This is pretty much going to end up as a Lemmings community, for all the fan stuff. A good home for Lemmings fans that is maintained is pretty hard to find.
In addition to those level packs that have been trickling in, I'll probably be adding more sections for Lemmings fan-stuff soon, maybe stuff like art and the likes. Additionally, I'll finally get to work on modifying the theme to make it feel more Lemmings-y.
