As Shadowbane has pointed out The Gilded Tarot has it's own subforum over in the Individual Deck Studies section.
To find it without the link look for Tarot Study Groups on the forum main page: http://www.tarotforum.net/index.php?
and then click the underlined 'Individual Deck Studies'. You will then see The Gilded Tarot group: http://www.tarotforum.net/forumdisplay.php?f=120
Post to any of the existing threads, you'll find an index of threads covered so far at the top of the group: http://www.tarotforum.net/showthread.php?t=27174
If you want to study a card that hasn't been covered yet just start a new thread.
