Hello, I've looked around on the wiki and I've seen good things, but also somethings we could change maybe:
1. Talk page to Message wall: A message wall is for new users easier to use. It's also always obvious who something wrote. And personal I find it looks better.
2. Protect some important pages (like the home page): This is to prevent spamming and vandalism on it. If somebody will change it he can ask an admin to unprotect the page for a short time.
These two change are the most important for now I think. Please say/discuss what you find about this in the comments below.
