Steve,
Right here on this page if you go up to the header and click the dropdown at "community" then click groups it will take you to the groups area where you can then click on the "Grizzly Green Monster Group". Roger Chandler has told me there should be an icon in the upper right corner to click on to upload images but I have tried both Firefox and Google Chrome and still find no such icon. The main thing though is that when I attempt to attach an image when responding in a thread I do not get the option to retrieve an image from "my computer", just the window asking for the url of the image. Hope you have better luck than I did.
