The Wiki section needs some work.
So you go to the Wiki section (I'm looking at the Silk Test one) and there is a list of items with a number of pages for each item. You click on an item with many pages and you get a brief summary of the section.
The Table of contents is to the right and it is not easy to read and requires a lot of scrolling to see everything in the list.
How about making better use of the main area with (say) the title and the first couple of lines of the Wiki entry shown (possibly by date).
Also, make searching more up front and centre so that users can easily find out how to search. Note that there is a message on this Wiki page asking how to search (ironic).
