Poor But Happy, Colombia message board, the granddaddy of them all.  It is a great site with ongoing posts of questions and answers on everything Colombian, political, tourism, marriage, food, fun, travel, popular and obscure.  Pictures  and links too.  Join and participate or just browse and read.  Most questions are begun and answered here, usually within minutes.

ColombiaBlog.com  Next to the above site, the Colombia Blog site has quickly grown to over 16 thousand articles and has a pretty well laid out entrance.  Once there, it is easy to navigate to the numerous forums from immigration to general discussions to a complete photo gallery from participants.

  Meetup.com Begun by Webmanco from the Poor But Happy, Colombia site so members can connect with each other in their cities in the U.S. and Colombia.  Also includes message board.  Must register but it's easy.  I've been to a meetup in Bogota and it was pretty fun.

Google Groups  Forums on visas, immigration and marriage issues.  Each link is a different group.

Good-Wife.com  Formerly Planet Love  Here's an odd message board about Asians, Latinos and Russians tucked away in a mail-order-bride type site.  It is sort of the Jerry Springer of message boards but does include some discussions worth reading for entertainment, along with some personal riffs.
