Hi Ken,
A first petty comment from me :) is about the symbol # that you are using in e.g. “the # of coins”, which looks a bit weird to me as I am more used to British English. I think that the word “number” would be more international.
Another comment I have is on the menu on the left. I think that perhaps the entries could be regrouped to distinguish between visitors who just come to see the site and members who are into editing it.
For instance, at the top of the menu I would only leave the entries that read-only visitors would be interested in. Still use the silver and gold graphs as separators between the two sets of entries but move e.g. the “How to edit pages” below them.
Perhaps the “How to join this site” could also be moved to be the first entry below the graphs, and the “Discussion Forums” to be the first entry above the graphs.
The general idea behind my comments is to help the read only visitors focus on their navigation menu.
On a more general note about this community forum, perhaps it could be useful to have a dedicated “Feedback” section for members to submit their wikis or pages for comments.
