I've seen a few forums now that have adopted bbcode for sortable tables and I wish we had them for CAG. These are great because people can dump pipe-delimited data into a table on the forum and users can sort by header. For instance, some people like to list by release date vs others who prefer alphabetical and this would serve both interests without separate lists.
Imagine on BF being able to not only sort by retailer, but by price comparison for certain titles. I really think it would revolutionize how CAG presents ads (among other things) making the site a one-stop shop.
