If you look through his ebay shop http://stores.ebay.co.uk/Black-Jax-Custom-Stencilsand go through the categories there are a lot of patterns that I recognise as being in the library and I think from other forums as well. I agree that the library should be only available to members with a certain number of posts, maybe 10, 15 or more. Maybe pattern central could be made private as well, I don't know the answer to this problem, just offering suggestions to combat it, It would not be a good thing if this behaviour made the pattern makers stop doing what they do on here, I for one appreciate all the time and effort they put in.
happy scrolling
