I'm working on a plugin to try to integrate the WDtN Short URL API into a forum. If I finish it (mainly trying to figure out how the hell to insert the link into a template), I'll ask Eric/Euan/FMB/WDtN in general if I can release it. Meantime though, it's still hidden on my main site.
Update: I've managed to get everything to work right except for the final link - it's always throwing my testing "Unable to generate short link" error at me.

Please don't PM me for support.
