Hello everybody!

I apologize if I'm sending this email to the wrong mailing list / group. If so, does anybody know where I should be asking wiki-related questions?
I think Haskell is a wonderful language and I would like to help the community in whatever way I can.

Currently I was looking at the 99 Haskell problems from the wiki, trying to solve them in as many ways as possible:
http://www.haskell.org/haskellwiki/H-99:_Ninety-Nine_Haskell_Problems

I have noticed there is a note saying that some of the solutions could do with reformatting. Indeed I have noticed that the solution pages aren't very consistent. I edited "the solutions for problem nr. 4" page:
http://www.haskell.org/haskellwiki/99_questions/Solutions/4
I added headlines, separated the alternative solutions into logical groups and there was one  (the Prelude implementation) which was mentioned twice.

Could somebody please have a look over the changes and confirm I didn't do anything wrong please? I have read the wiki editing guide, but I am unsure if this a good format to use for the "Solutions" pages.

Many thanks!
