No Prob Russ, I only found out how to do it recently and it's dead easy!
1. Right click on the long address bar just underneath the back & refresh etc.
2. Left click on copy
3. Go back to the Up-North site (if you click the centre of the top right boxes and make sure you can click on your Ebay and use the back button to go back to the Upnorth page at the end of what you have been writing), make sure there is a space after the last word, Right click again then left click on paste and the address will be there. You can do the same with writing on a page by a left clickand chnging the colour of the writing and select copy.
