Welcome to the Sammio experience 'bartfast. Fellow Douglas Adams fan by any chance?
Looking forward to seeing some pictures of your progress, most people posting pictures on here use -
www.photobucket.com
You'll need to register with them (free), then follow the simple instructions to upload pictures stored on your computer to their server. Once they're in your photobucket 'album' you just hover over the image you want to post, move the cursor onto the 'img code' tab on the menu that drops down Click on it and the word 'copied' will briefly appear. Switch back to the madabout forum and put the cursor where you want the picture to appear in your post, then right click followed by 'paste' and the code will appear. Once you submit the post the images will be directly embedded in your entry so we can all see them.
Good luck with posting the pics and with your build. Sounds like you've got a decent donor which is a good way to start. Wish I'd thought of that...
