This plugin rocks! I agree there's a lot of trash online, and thats where it should stay. This Plugin, rocks. The SEO functionality is there. This makes a huge difference for webmasters. I have recently installed the Link Exchange on all 4 of my most popular sites. What I LOVE about this plugin is that it tracks the back-links - saw results in as little as 24 hours.
It would great if in the "Links" section (in the back-end), you could "SHOW" where each category is (in the back-end) "ie: http://yoursite.com/links/?catid=6/" (for the free version)
That way I know what link exchange category each link is sitting in (rather than flipping back and forth thru the front-to-back end of my blog) to exchange with other websites. SAME goes for the PRO version, something similar would be nice too. to see it in the backend.
