I've tried to find the thread in the lounge that you are referring to, but I can't seem to find it. To post a link to the thread, once you're there, highlight the ULR at the top of the page, press
Ctrl and
C (copy). Then in a new post, just press
Ctrl and
V (paste). That will post the link in a thread.
If you want to post the pic of the buggy in question, right click on the pic. Then click on properties. Then do the same copy and paste described above. But when you go to paste it in a new post, click on this icon above the text box

and paste the URL in the box that shows up.
