Made some changes to the page on creating delimited lists to collections ( and vice versa ), including putting a section on how to create a delimited list using just SQL (via the SYS_CONNECT_BY_PATH function), as well as revisiting the wording on quite a few sections on that page.
I also noticed a slight problem on the main page in that the text for one of the menu items was out of sync with the rest of the pattern, i.e. it was red when it should have been green.
