Antony,
We can gladly help get you going. Unfortunately, we don't specifically point out sites that are using JLinked as they may not want people 'testing' on their sites. You're free to look through the forums and find links to some pages, but I don't have any examples of "this site implements these features".
As to your issues, if you can explain a bit more about what you're trying to configure and what's going wrong, we'll do what we can go get you going. On this site, we obviously implement the SCLogin module in the top right. Also, on our Job Openings page, we're using the Apply button. Feel free to try clicking on that if

In general though, are you having issues with the SCLogin module appearing or the social modules, like Member Profile an such. With that, we can help narrow down what may be wrong. Seeing a page with issues is definitely the best way for us to diagnose things though.
Thanks,
Alex
