This is the website where you can make the little birdie icons and attach them to your signature... www.finchbreederdatabase.com
It was complicated for me, but others are pros at it. I went through the HELP link, scrolled down to where Signature was and then clicked on the OPTIONS link. That's how I did mine, although others might know an easier way. Btw, You don't have to be an actual breeder to create a profile on this forum, so no worries about that. Good luck and have fun
