Do not have time now, but will read it later - sounds interesting. Thanks for posting, fingers! As for posting links - you just copy the url address and paste it into the text of your post. Then the url address will appear in your post, just the way the url addresses appear in mine, above this text. If you want to go the fancy route, you can make the link read whatever you like but point to the url address. It looks prettier, but requires extra effort. If you want to do that, there is an icon with the globe (blue and green) and a link beneath it on top and across the window in which you enter the text of your post. You would need to press on that icon and enter the text you want visible on top and the url address on the bottom in the little window that will pop up for you.
