About [[MediaWiki:Allmessagestext/en]]

I'm not so sure about the fresh beginning, but an index is, I think, a very good starting point for improving the help pages. I have started drafting one here, which you are welcome to work on there or copy over to a different draft, as I don't have much time to spare at the moment. The list as yet is not complete and it hasn't been organised into sections, but it's a start.
