You're welcome to use it if you want to get a link page started, and I'd be glad to help - you can also add comment sections on the page to get user input/contributions so if anyone else has some links they can comment them there. I eventually want to more fully formalize user contributions to pages so that they can be used as crowdsourced freeform sites, if theres enough interest out there.
