Hey Drock,
As noted above, we fully intend on holding TerraClips layout contests and we also have a dedicated TerraClips Software layout planner schedule for production. There's a very creative group around here who've been building modular layouts with TerrainlinX for years. We'd be pretty silly not to take advantage of that pool of knowledge
More support materials to come as we move forward. In the mean time do check out the layouts people have already provided within this very forum. There's some great stuff in here
