Thanks folks, I appreciate all your comments.

Now for the next bit ... I hope I have not dropped a clanger. As detailed in my readme the leash uses Easy Pose technology. In the same way as we often edit existing CR2's to match new models I adapted an Easy Pose item from the freestuff. Oola is not a commercial item, I'm giving her away for free. Ajax the author of Easy Pose has contacted me asking for clarification which I have replied to. I've made it clear that I'm very willing to address any issues. I don't think I got it wrong but I'm human. I'd rather be safe than sorry so until this is clarified I've removed Oola from my server, I'd much rather err on the side of caution.
