Thanks for the tip. Thanks to the very functional milsurps.com software, posting a hotlink is so simple - 4 keystrokes - that even I learned how to do it.
1. Right click in URL window while on the Gunbroker listing (that's the long, skinny one at the top that starts with Military Surplus Collectors Forums.)
2. Click 'copy' in the window that opens.
3. Go back to the reply window here.
4. Right click to open a window, then click paste.
Nothing to it.
